Question

find two supplementary angles which are in the ratio 13:5​

Answer 1

Answer:

13x+5x=180°

x=10°

First angle= 130°

Second angle=50°

Step-by-step explanation:

Answer 2

Answer:

first angle=130°

Second angle=50°

Step-by-step explanation:

Let the two angle be x.

So the angles will be 13x:5x

13x+5x=180----(Supplementary angles are of 180°)

18x=180

x=180/18

x=10

First angle=13x=13×10= 130°

Second angle=5x=5×10=50°
