Question

use the properties of triangles to find the unknown angles :-​

Answer 1

From figure we can see that two sides are equal so the triangle is isosceles

So the remaining two angle are equal

Let one of remaining two angles be x

x+x+50° = 180° ( both remaining angles are equal )

2x + 50° = 180°

2x = 130°

x = 130°/2 = 65°

After labelling the figure ( drew in a hurry )

angle y = angle A + angle C ( opposite angles equal to exterior angle )

angle y = 65° + 50° = 115°

Similarly angle x = angle A + angle B

angle x = 65° + 50° = 115°
