Question

if angle A is 5 times its complementary angel and 5/7 of its supplementary angle then find the measure of angles A​

Answer 1

$\huge\mathcal{\fbox{\fbox{\pink{answer}}}}$

Let the angle be x

Therefore, other angle is 5x

We know now,

x + 5x = 90

6x = 90

x = 15

Therefore other angle is 15 (5) = 75°

Answer 2

two angle are complementary when their measures added to 90 degree

it is given that A is 5 times

so,

x+5x = 90°

thus, 6x= 90°

x= 90/6

x=15°

therefore other angle is 5

thus, 5(15)=75°

hope, this is helpful for you
