Answer:
m angle A = 68deg
Step-by-step explanation:
Since they're complementary, they add up to 90deg
you solve this by first finding x
(4x-28) + (x-2) = 90 >> add the left side
5x-30 = 90 >> add 30 from both sides
5x = 120 >> divide by 5 on both side to get x alone
x = 24
now you know x is 24, you substitute it in m<A since you're finding the measure of it
(4(24) - 28)
96 - 28
68
you can check by finding the value of m<B (22deg) and adding it to m<A and it will equal to 90deg
