We know that angle 101 and its interior angle next to it will equal 180 because it's a straight line.
180-101= 79 degrees
Find 3rd angle of triangle.
180= 38+79+y
180= 117+y
Subtract 117 from both sides
63= y
That is the interior angle by x. X plus 63 also equal a line, or 180 degrees.
180= 63+ x
Subtract 63 from both sides
117= x
Hope this helps! :)
