Question

Two angles of a trangle are equal to each other and the third angle is the sum of the other two. Find all the angles of the sum​

Answer 1

Two angles of a triangle are equal. Hence, it is a Isosceles triangle.

Let the angle be x.

---------------------------------------------

So, x + x + (2x) = 180° (Angle Sum Property)

= 2x + 2x = 180° (adding xs outside the bracket)

= 4x = 180° (adding all xs)

= x = 180° / 4 (transposing 4 to the RHS from the LHS)

= x = 45°

Angle 1 = 45°

Angle 2 = 45°

Angle 3 = 90°
