If the measures of two complimentary angles are 7x and 11x , then find x
2 answers:
Answer:
x = 5
Step-by-step explanation:
Complementary angles are two angles whose sum is 90º
So, if we have two complementary angles 7x and 11x we know that their sum is 90
We are going to write the equation and solve for x:
Therefore, x would be 5. And the angles would be 7(5) = 35º and 11(5) = 55º
As you know that sum of complementary angles equal 90°
so,
7x + 11x = 90
18x = 90
x = 90/18
x =5
so,
option A is the correct one.
