Question

I don't know how to solve this. Can someone please help me?

Answer 1

Explanation:

you divide and multiply the angles to find the x value

Answer 2

When the 2 sides of a triangle are equal ( in the figure shown both sides are 21) then the two bottom inside angles would aldo be equal to each other.

The three inside angles of a triangle need to equal 180 degrees.

Subtract the top angle from 180 and then divide by two:

180 - 38 = 142

X = 142 /2

X = 71 degrees.
