Question

an exterior angke of a triangle is110° and its two opposite interior angles are equal. find the measures of two equal interior angles​

Answer 1

Answer:

LET ONE ANGLE BE X

∴ 2X = 110

⇒ X = 110/2

⇒ X = 55°

Thus the two interior angles measure 55°

Answer 2

Answer:

let the 2 opposite interior angles be x°.

By using exterior angle property of triangle

x° + x° = 110°

2x° = 110°

x° = 110° ÷2

x° = 55°

therefore the 2 equal interior angles is 55° and 55°.
