Question

The three angles of triangle are in the ratio 2 : 7:5.
Find the measure of each angle.
plz tell​

Answer 1

Answer: I am giving you a example

Let common multiple of all the angles is x

Thus, angles of triangle are given by 5x, 3x and 7x

By angle sum property of triangle,

5x+3x+7x=180

∴15x=180

∴x=12

Thus, angles of triangle are,

5x=5×12=60  

0

 

3x=3×12=36  

0

 

7x=7×12=84  

0

 

All the three angles are acute angles. Thus, triangle is acute angled triangle

Answer 2

Answer:

Step-by-step explanation:

Angles in a triangle = 180

So, 2x + 7x + 5x = 180

14x = 180

x = 180/14

x= 90/7

Angle a = 2*90/7 = 25.7

Angle b = 7*90/7 = 90

Angle c = 5*90/7 = 64.2
