Answer» Answer: ANGLE A plus angle B plus angle C = 180 (angle SUM property) angle A = 45 angle B = 45 let angle C = x x plus 45 plus 45 = 180 x plus 90 = 180 x = 180 - 90 x = 90 angle C = 90

Answer»

Answer:

ANGLE A plus angle B plus angle C = 180 (angle SUM property)

angle A = 45

angle B = 45

let angle C = x

x plus 45 plus 45 = 180

x plus 90 = 180

x = 180 - 90

x = 90

angle C = 90
