Answer 2

Answer:

The angle of triangles are 20, 70, 90 respectively to the ratio of 2:7:9.

Step-by-step explanation:

Given:

Find the angle of a triangle whose are in ratio 2:7:9

To find:

Write the types of triangle

Solution:

2x + 7x + 9x = 18 x

Sum of angles of a triangle = 180

18x = 180

x =$\frac{180}{18}$= 10

the angles are 2x = 2 $\times$10 = 20

7x = 7 $\times$ 10 = 70

9x = 9 $\times$10 = 90

Result:

The angle of triangles are 20, 70, 90 respectively to the ratio of 2:7:9.
