Question

<A and <B are complementary

angles. if m<A =(6x-4)° and <B=(x+17)° then find the measure of <A​

Answer 1

<A = 62

Explanation:

<A and <B add up to 90 degrees. Definition of Complementary.

<A + <B = 90

(6x - 4) + (x + 17) = 90

7x + 13 = 90

7x = 77

x = 11

<A = 6x - 4

<A = 6(11) - 4

<A = 66 - 4

<A = 62
