Answer 1

Answer:

138

Step-by-step explanation:

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

Let's examine the given triangle. Angle x is an exterior angle. <BAC is an interior angle of the triangle. <x and <BAC are adjacent angles. Angles B and C are not adjacent to <x. "Remote" means far away. Of all interior angles of triangle ABC, angles B and C are the remote interior angles of exterior angle x.

Now look at the theorem above. It states that the measure of any exterior angle of a triangle equals the sum of the measures of its remote interior angles.

In this case, <x is an exterior angle. Its remote interior angles are angles B and C. The measure of <x is equal to the sum of the measure of angles B and C.

m<x = m<B + m<C

m<x = 68° + 70°

x = 138
