Question

the angles of a triangle are in the ratio 2:3:7 find all angles
​

Answer 1

Step-by-step explanation:

Given,

Ratio of angles of triangle are 2:3:7

Let the angles be 2x, 3x, and 7x

Sum of all angles in a triangle= 180(ASP of triangle)

2x + 3x + 7x = 180

12x = 180

x= 180/12

x= 15

first angle =

2x = 2× 15

= 30

second angle =

3x = 3×15

=.45

third angle=

7x = 7×15

= 105
