Question

The measure of two angle are in the ratioc7:8 and they are supplementary angle. What are there measure in degrees

Answer 1

Hello!!
Let's take their degree as "x"
7x+8x=180
15x=180
x=180÷15
x=12
so,7x=7(12)=84
8x=8(12)=96

Answer 2

let the ratio be X
so first angle equal to 7 x
second angle equal to 8 x
7 x + 8 X equal to 180
15 X equal to 180
X equal to 180 by 15
X equal to 12
hostel girl equal to 84 degree
second angle equal to 96 degree
