Question

an angle is equal to 5 times its complement determine its Measure

Answer 1

75 is your answer of your questions

Answer 2

let the first angle be x
then the second angle will be 5 times of x i.e. 5x

$x + 5x = 90 \\ 6x = 90 \\ x = \frac{90}{6} \\ x = 15$
first angle =x=15
second angle =5x=5(15)=75
