Question

Find angles in isosceles triangles...

Answer 1

68

Explanation:

Given is an isosceles triangle, therefore measures angles opposite to equal sides would be equal.

Hence,

56° + 56° + x° = 180°

112° + x° = 180°

x° = 180° - 112°

x° = 68°

x = 68

Answer 2

• x = 68°

Explanation:

The triangle is isosceles as two sides have same length

Angles opposite to same sides have same value, therefore two of them equal to 56°

• x = 180° - 2*56°
• x = 180° - 112°
• x = 68°
