Question

the sum of the angles of triangle is 180degree and the angles are in the ratio of 1:2:5 find the measure of each angle​

Answer 1

Step-by-step explanation:

Let be angle x = x + 2x + 5x

According to question

Sum of the angles of triangle = 180°

x + 2x + 5x = 180°

8x = 180°

x = 180/8

x = 22.5

× = 1 × 22.5 = 22.5 Ans

2x = 2 × 22.5 = 45 Ans

5x = 5× 22.5 = 112.5 Ans
