AOC and BOD are diameters of a circle, centre O. Angles BAD and CDA are 90°. Prove that triangle AND and triangle DCA are congruent
Please help me, i have a test tomorrow and i am confused ⭐️
Answer:
By using SAS which stands for Side, Angle, Side.
Step-by-step explanation:
This means that if we have two angles and side measures that are equal to the corresponding angles and side measures of the other triangle then they are congruent.

The hyperbola has two vertices at (-2,0) and (2,0)
We have given that the equation
[tex]\frac{x^2}{4}-\frac{y^2}{9}=1[/tex]
What is the equation of the hyperbola?[tex]\frac{x^{2} }{a^2}+\frac{y^2}{b^2} =1[/tex]
Compare the above equation of the hyperbola with given equation
therefore a=2
vertices are (-a,0) and (a,0)
Therefore the vertices are (-2,0) and (2,0)
See the graph of the hyperbola in link given below.

The side of a regular pentagonal pyramid is 6 feet long. The slant
height of the is 7 feet long. What is the lateral area of the pyramid.
Answer:
105 sq ft.
Step-by-step explanation:
LA = slant height time perimeter of the base divided by 2.
Perimeter = 5(6) = 30
LA = 7(30)/2 = 105 sq ft.

solve the system by substitution 3x-y=10 2x=y
Answer
X=10 and y=20
Step-by-step explanation:
since y=2x, you need to substitute that into the equation to get:
3x-(2x)=10
And evaluate:
x=10
Then substitute 10 into the equation: 2x=y:
2(10)=y
evaluate:
20=y
Now go back to the original equation to check your answer and substitute the values in:
3(10)-(20)=10
30-20=10
10=10

PLEASE HELP!! What do most marketing entrepreneurs do to prepare to launch their
businesses? (this is actually business not math but)
Marketing entrepreneurs choose a marketing niche first to prepare to launch their business. Thus, option B is correct.
What is marketing niche?The portion of a market that a particular product is targeted toward is called a niche market. The product's market niche determines its price range, level of production, target demographics, and feature set that is intended to address a particular market need. Additionally, it is a small market sector. A product or service may occasionally be created specifically to meet the needs of a niche market.
Not all products can be classified by their market niche. The highly specialised niche market competes against numerous super companies and strives to remain viable. Even well-known companies develop products for specific markets; Hewlett-Packard produces separate machines in addition to all-in-one printing, scanning, and faxing units that are aimed at the home office market.

Given: EL≅KP Prove: KE≅LP
Answer:
See Below.
Step-by-step explanation:
We are given that:
[tex]EL\cong KP[/tex]
And we want to prove that:
[tex]KE\cong LP[/tex]
Congruent chords have congruent arcs. Therefore:
[tex]\stackrel{\frown}{EL}\, \cong \, \stackrel{\frown}{KP}[/tex]
Arc EL is the sum of Arcs LP and PE:
[tex]\stackrel{\frown}{EL}\,=\, \stackrel{\frown}{LP}+\stackrel{\frown}{PE}[/tex]
Likewise, Arc KP is the sum of Arcs KE and PE:
[tex]\stackrel{\frown}{KP}\, =\, \stackrel{\frown}{KE}+\stackrel{\frown}{PE}[/tex]
Since Arcs EL and KP are congruent:
[tex]\stackrel{\frown}{LP}+\stackrel{\frown}{PE}\, =\, \stackrel{\frown}{KE}+\stackrel{\frown}{PE}[/tex]
Subtraction Property of Equality:
[tex]\stackrel{\frown}{LP} \, \cong\, \stackrel{\frown}{KE}[/tex]
Congruent arcs have congruent chords. Therefore:
[tex]LP\cong KE[/tex]

A bag contains 4 apples, 6 pears and 8
oranges. What is the probability of
picking an orange? (in simplest form)
Using the question above, what is the
COMPLEMENT of picking an orange from
the bag?
Answer:
The probability of picking an orange is 8/18, or 4/9.
8/18 of the fruits are oranges, so 10/18 of the fruits are not oranges. The complement of picking an orange is 10/18 or 5/9.
Step-by-step explanation:
There are 4 apples, 6 pears, and 8 oranges. That adds up to 18 fruits. 8 of those are oranges, so the probability of picking an orange is 8/18, or 4/9 simplified.
The complement means all outcomes that are NOT the favorable outcome, or in this case, all outcomes that are not oranges. There are 8 oranges out of 18, so there are 10 fruits that are not oranges. This makes the complement 10/18, or 5/9 simplified.
Answ2/6 or 33% chance of getting an apple, 3/24 or 13% of getting a pear and 13/24 or 54% chance of getting an orange hope that helps.er:

y=x²+2x+2
First, we should try to change the last number in a way so we can factor the entire thing
y=x² + 2 x + 1
tooo make it look like y=(x + 1 )²
the only difference between the original y=x² + 2x + 2
and the factor-able y=x² + 2x + 1 is simply changing the
2 to a 1 (Since we can't randomly change the 2 to a 1, we can add 1 and subtract a 1 to the equation at the same time to keep it balanced.)

Find, to the nearest degree, the

The angle that the wire makes with the ground is 36.87° with horizontal.
What is a trigonometric function?The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.
The given situation is making a right-angle triangle,
By Pythagoras' theorem in the triangle.
Base = √(100² - 60²) = 80 foot
By tan trigonometric function,
tanx = 60/80
x = 36.87°
Hence "The wire's angle with the ground is 36.87° with respect to the horizontal".
