Question

ANGLES OF TRIANGLE are in ratio 1:3:8. Find measures of three angles of triangle

Answer 1

1x+3x+8x=180

12x=180

x=180-12

x=178

178÷1=178

178÷3=57.3

178÷8=23.5

Answer 2

Hey !

Answer:

A = 15°

B = 45°

C = 120°

Step-by-step explanation:

Let the angles of the triangle with ratio of angles 1:3:8 be A , B & C respectively .

Then , by angle sum property of triangle :

A + B + C = 180°

1x + 3x + 8x = 180°

12x = 180°

x = 15°

Therefore ,

A = 15°

B = 45°

C = 120°
