Answer:

The angle sum property of a triangle is 180° so to find the angles we need to sub 20° from 180°......

( 180°-20°) = 160°......

Hence there are two angles we need to divide them with 2.

160°/2 =80°......

so both the angles are 80°.

Now to verify whether the ans is correct or not

We can add all the Angles and see whether they are 180° or not.....

(20°+ 80°+80°)= 180°..... (so can conclude that the answers are correct)

Hope it helps.......
