Answers
Answer:
Area = 169.7 in^2
Step-by-step explanation:
The two given angles are 90 and 60 degrees. Since a triangle's angles always add to 180 degrees, the third angle is 30 degrees. The is known as a "30-60-90 triangle." It is a special right triangle that has side length values which are always in the same relationship with one another.
The sides of the 30-60-90 triangle ratio are:
Side opposite the 30° angle is x
Side opposite the 60° angle is x*√3
Side opposite the 90° angle is 2x

Answer:
-1=x
Step-by-step explanation:
2-11x=4x+17 Given
2(+11x)-11x=4x+(11x)+17 Subtract 11x from both sides
2=15x+17 Simplify
2 (-17)=15x (-17) +17 Subtract 17 from both sides

Since its on a workbook, I think what your supposed to do for the shapes is measure the given side, say the line for the first question for a square was 2 inches, then you would have to put the rest of the sides 2 inches as well, paying attention to the angle measures.
each angle is 90° in a square, 120° for a hexagon, and the rest should hopefully be do-able.

According to the data, Manny should spend less on food and clothes and put the money towards his credit card payment.
We know the expression for the monthly payment is given by:
[tex]\rm M = P \frac{r}{(1-(1+r)^{-nt})}[/tex]
Where P is the principal amount
r is the interest rate.
M is the monthly payment
t is the time
n is the number of times the amount compounded.
Thus, Manny could spend less on food and clothes and put the money towards his credit card payment, as she is spending $368 on foods and clothing.

Answer:
5. angle A=40
6. angle C= 80
7. angle C= 110
Step-by-step explanation:
In all three questions, it says angle B= angle A+ angle C
So for each when it gives you angle B and one of the others, you just subtract either angle A or angle C from the total angle (B) to find the other. For example, for question 5, it asks for angle A saying that B is a right angle and c equals 50. Well, a right angle is 90 degrees. So to find angle A, you do 90-50.
Guess the rule and enter the missing number in the sequence. 23, 20, 17, 14,
Answers
Answer:
11
subtract 3
Step-by-step explanation:
The numbers are getting lower in value as you go,
So that means it is a subtracting sequence,
Take the first two numbers and subtract them,
23 - 20 = 3
So now subtract 3 from the others and see if it works,
20 - 3 = 17
17 - 3 = 14
14 - 3 = 11
11 is the missing number
Yep, it works,
Hence the sequence is to subtract three.
Rule: subtract by 3 every number in the series
