Question

Find the measure of angle A

can you show me how to solve this problem​

Answer 1

angle a = 20

Explanation:

So like the person above me said

180-140=40

40 divided by 2 is 20

(I don't know if I can delete answers so I just fixed this one)

Answer 2

A = 20 degrees

Explanation:

Both legs of the triangles are 2x and equal, so we know that the triangle is isoceles. That means both acute angles are equal as well.

In a triangle there are 180 degrees

180 - 140 = 40

40 remainding degrees/ 2 equal angles

A = 20 degrees
