Answer:
y=58
x=32
Explanation:
two remote interior angle is congruent, equal, to the exterior angle. so 50+88 is equal to y+86. add the two numbers and set the equations equal to each other. 138=y+86. then subtract 86 from both sides. y=58. knowing that y is 58 we can now solve for x. the interior angles of a triangle always equal 180. 58+90, the right angle, equals 148. 180-148=32 therefor x=32
