Respuesta :

The angle x and 70 are alternate interior so that means they measure the same.

In an isoceles triangle the base angles are the same so that means that both the x angles are 70.

Now we can subtract their sum by 180 to find the measure of angle 1.

180 - (70 + 70) = 40

So the measure of angle 1 is 40.

Hope this helps :)

Using the definition of isosceles triangles, m∠1 = 40°.

What is an Isosceles Triangle?

An isosceles triangles is a triangle that has two congruent base angles and two congruent sides.

Thus:

x = 70° (alternate angles are congruent)

Therefore:

m∠1 = 180 - 2(70) (triangle sum)

m∠1 = 40°

Therefore, using the definition of isosceles triangles, m∠1 = 40°.
