Answer:

x=54º

y=63º

Step-by-step explanation:

Let the other angle in the triangle be zº.

Because the measure of a line is 180º, zº=180º-117º=63º.

Because the triangle is isosceles yº=zº=63º.

The sum of the measure of the angles in a triangle is 180º. So, 63º+63º+xº=180º.

126º+xº=180º

xº=54º
