Two angles are complementary when they add up to 90 degrees<span>
</span>Two angles are supplementary when they add up to 180 degrees
angle = x
supplementary angle = (180-x)
complementary angle = (90-x)
180 - x - 40 = 2(90-x)
140 - x = 180 - 2x
-x + 2x = 180 - 140
x = 40°

Answer:
D. 5 < x < 9
Step-by-step explanation:
The third side cannot be any shorter than the difference of the other two sides: 7 -2 = 5. It cannot be any longer than the sum of the other two sides: 7+2 = 9. It cannot be equal to either of those values. So, we must have ...
5 < x < 9
Answer:
Step-by-step explanation:
Move the b over to the other side to get the 2a alone.
2a=c-b
Then divide the entire equation by 2 to get a instead of 2a.
1 inch= 2.54 cm
Divide 7 by 2.54.
7/2.54= 2.75591
So, 7 cm is about 2.8 inches. (rounded up)
I hope this helps!
