Question

One of the equal angles of an isosceles triangle is 50°. Find all the angles of this triangle.​

Answer 1

Answer:

Let x to be the third angle.

»» x + 50 + 50 = 180°

»» x + 100° = 180°

»» x = 180-100 = 80°

So, angle x = 80°

Hence the three sides are 50° , 50° and 80° .

hope it helps you.

Answer 2

Answer:

x + 50° + 50° = 180°.

x + 100° = 180°.

x = 180° - 100°.

x = 80°.
