What is the value of x in the triangle?
45°
4
х
45°
OA. 4
B. 2
OC. 412
OD. 212
Answer:
D
Step-by-step explanation:
use the sine or cosine ratio in the right triangle.
using the sine ratio and the exact value
sin45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2x = 4[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
x = 2[tex]\sqrt{2}[/tex]
The value of x is 2√2.
Hence the correct option is D.
Given that a right triangle with acute angles 45° each, and hypotenuse is 4 units,
we need to find the length of the perpendicular,
In a right triangle, the length of the perpendicular (also known as the altitude) can be found using trigonometric ratios.
In this case, since we have an angle of 45°, we can use the sine or cosine function.
Let's use the sine function to find the length of the perpendicular:
sin(45°) = opposite / hypotenuse
sin(45°) = perpendicular / 4
1/√2 = perpendicular / 4
perpendicular = 4/√2
perpendicular = 2√2
Hence the value of x is 2√2.

answer the question below. Type your response in the space provided What is the height of the cylinder in the diagram? Round your answer to the nearest whole V = 904.78 cm³ 6cm
Answer:
For this question, we use the formula for the volume of a cylinder.
(formula for vol. of cylinder)
V = π[tex]r^{2}[/tex]h
Where 'π' represents pi(22/7 or 3.14), 'r' represents the radius which is being squared, and 'h' stands for the height.
We utilize the information that we know:
Radius = 6cmVolume = 904.78Which we then plug into our equation(volume of cylinder formula):
V = π[tex]r^{2}[/tex]h
904.78 = 3.14(6^2) · h
Next solve for the h(height).
904.78 = 3.14(36) · h
904.78 = 113.04 · h
904.78 = 113.04h
/113.04 /113.04
8.00406935598 = h, which we round to 8.
8 centimetres is the height of this cylinder.

EXPLANATION:
Box A contains only 20-cent coins and Box B contains only 50-cent coins. The number of coins in Box A is twice the number of coins in Box B. The amount of money in Box B is $1.60 more than the amount of money in Box A. How many 20-cent coins are there in Box A?
Answer:
There should be 16, 20 cent coins in the box
Step-by-step explanation:
First we have to do 1.60 x 2 which equals 3.2
Then we divided by 0.20 because the equals the 20 cent coins
We get 16
We can check our work by 0.20 x 16 and that gives us 3.2

Find the area of the parallelogram 9.9in 5.5in
Answer:
54.45 in²
Step-by-step explanation:Let the base and height be 9.9 inches and 5.5 inches respectively.
Formula;
Area of parallelogram = Base × Height
Substitute the base and the height in the formula:
⇒ Area of parallelogram = Base × Height⇒ Area of parallelogram = 9.9 × 5.5Evaluate the area of the parallelogram:
⇒ Area of parallelogram = 9.9 in × 5.5 in⇒ Area of parallelogram = 54.45 in²Answer:
54.45 in²
Step-by-step explanation:
Formula
Area of a parallelogram = base × height
If you turn the parallelogram so that the sides that measure 9.9in are the base, you will see that 5.5in is the height (refer to the attached diagram). Therefore, we can use the formula with these values to calculate the area.
Given:
base = 9.9 inheight - 5.5 in⇒ area = 9.9 × 5.5 = 54.45 in²

Answer:
x=16, y=26, z=13
Step-by-step explanation:
opposite angles are congruent so (3x+30)=(4x+14)
Solve for x
x=16
adjacent sides are supplementary so insert x in both equations just to make sure it is correct and you get 78
so 3y=78 and 6z=78
solve for y and z
y=26, z=13

4. Find the surface area of the triangular prism:
5 ft
5 ft
3 ft
14 ft
8 ft
Shows work please
Answer:
276 ft²
Step-by-step explanation:
The total surface area of a prism is the sum of its lateral area and the area of its bases. Here, the bases are two triangles, and the area of the sides is that of three rectangles.
base areaThe area of a triangle is given by the formula ...
A = 1/2bh . . . . where b is the base of the triangle, h is its height
We have two identical triangles, so their total area will be ...
A = 2(1/2bh) = bh = (8 ft)(3 ft) = 24 ft²
lateral areaThe sides of the prism are rectangles, all with the same length: 14 ft. Their total area will be that length multiplied by the total of the rectangle widths. That total is the same as the perimeter of the triangular base:
P = 5 ft + 5 ft + 8 ft = 18 ft
Then the lateral area is ...
lateral area = Ph = (18 ft)(14 ft) = 252 ft²
total areaThe sum of the base area and lateral area is ...
(24 ft²) +(252 ft²) = 276 ft² . . . . area of the triangular prism
what is the 41st term of 8,17,26
Answer:
368Step-by-step explanation:
We can see that 9 is being added to each term.
Thus, we obtain the following rule:
8 + 9(x - 1)To make this easier, let's simplify the rule.
⇒ 8 + 9(x - 1)⇒ 8 + 9x - 9⇒ 9(x) - 1Substitute 41 as "x" to obtain the 41st term:
⇒ 9(41) - 1⇒ 368The value of 41st term of sequence 8, 17, 26 is,
⇒ 368
What is Arithmetic sequence?An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.
Given that;
The sequence is,
⇒ 8, 17, 26.
Now, The common difference is,
⇒ d = 17 - 8 = 9
⇒ d = 26 - 17 = 9
Thus, The sequence is in arithmetic.
Hence, The value of 41st term of sequence 8, 17, 26 is,
⇒ a + (n - 1)d
⇒ 8 + (41 - 1) 9
⇒ 8 + 369 - 9
⇒ 8 + 360
⇒ 368
Thus, The value of 41st term of sequence 8, 17, 26 is,
⇒ 368
