Answer:
x = 7
Step-by-step explanation:
The angle adjacent to the 70 degree angle is also 70 degrees. We assume that there are four 90-degree angles in the center of the figure. Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).
Solving 8x - 36 + 70 + 90 = 180 for x:
8x - 36 = 20, or 8x = 56.
Dividing both sides by 8 yields x = 7.
Answer:
19 lbs and 8 oz
Step-by-step explanation:
12 + 6 = 18 13 + 11 = 24 24 oz = 1 lb and 8 oz 1 lb and 8 oz + 18 = 19 lbs and 8 oz
-2.4n-3+-7.8n+2
you combine like terms
(-2.4n+-7.8n)+(-3+2)
= -10.2n-1
Answer:
D
Step-by-step explanation:
This is because they are both mulitplied by two so they are still equivalent
Answer:45
Step-by-step explanation:
First, you need to calculate the area of the square.
(LxW)= 25.
Then, calculate the area of the triangle
(1/2BH)=5x(8/2)=5x4=20
Now, just add 20+25= 45
