Question

find the measure of the angles of triangle ABC if its angles are in the ratio 1:3:5​

Answer 1

Answer:

20,60,100

because 1:3:5= 1x:3x:5x

1x+3x+5x=180°

9x=180°

x=20°

then angels are 20°,60°,100°

Answer 2

Answer:

A=20,B=60,C=100

Step by step explaination:

Sum of the ratio = 1:3:5

= 1+3+5=9

Sum of all angles in a triangle=180°

angle A = 1/9×180

=1×20=20

angle B=3/9×180

=3×20=60

angle C=5/9×180

=5×20=100

Verification:

Sum of all angles in a triangle =180°

angle A+ angle B+ angle C=180°

20+60+100=180
