IM STCK PLZ HELP!!! THANK YOU :)
lesya [120]

Answer:

x = 81, y = 68 and z = 99

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

z is an exterior angle, thus

z = 63 + 36 = 99

x and z form a straight angle and are supplementary, so

x + z = 180, that is

x + 99 = 180 ( subtract 99 from both sides )

x = 81

The sum of the 3 angles in a triangle = 180°, thus

z + y + 13 = 180, that is

99 + y + 13 = 180

112 + y = 180 ( subtract 112 from both sides )

y = 68
