Answer 2

Angle Sum property

The Angles of a Triangle add to a straight angle, 180°.

Given, Each equal angle of a triangle is 10 more than 1/2 of the third traingle.

Let x be the third angle

According to the question,

Equal angles = 10 + x/2

Now,

sum of is 180°

( 10 + x/2) + ( 10 + x/2) + x = 180

20 + x + x = 180

20 + 2x = 180

2x = 180 - 20

2x = 160

x = 80°

Therefore the Angles are x = 80°,

10 + x/2 = 10 + 80/2 = 10 + 40 = 50.

The angles of the triangle are 50, 50, 80°
