you have some serious typing problems. I have no idea what those weird expressions mean.
The sum of the angles of a triangle is 180°
So add them up and solve for x. Then use that to get your angle measures.
In the triangle below, suppose that =m∠W−7x5°, =m∠X−3x2°, and =m∠Yx°
.Find the degree measure of each angle in the triangle.
