Question

The two interior angles on one lateral face of a pyramid-shaped

paperweight measure 35° each. What is the measure of the unknown
angle?

Answer 1

As eudora states: B).110 is the correct answer.

Answer 2

Option (B)

Explanation:

From the property of a triangle,

Sum of all interior angles of the triangle is 180°

By applying this property in the given triangle IHK,

m∠HIK + m∠IKH + m∠KHI = 180°

m∠HIK + 35° + 35° = 180°

m∠HIK = 180° - 70°

= 110°

Therefore, measure of the unknown angle of the given triangle is 110°.

Option (B) will be the answer.
