Help please lol I’m confused

40 degrees = x

Step-by-step explanation:

As you can see in the picture, there are two lines that indicate that those two lines are equal. So, this triangle is an isosceles triangle, and the base angles of an isosceles triangle are equal. To identify the base angle, check the angles opposite to the side equal. So, we find that 70 is a base angle, so there are two 70 degrees  angles. So,

70 + 70 + x = 180 (The angle sum property of triangles)

=> 140 + x = 180

=> x = 180 - 140

=> x = 40

If this helped, please mark me as the brainliest!

Thank you!
