Question

an exterior of a triangle is 140. one of its interior opposite angles measures 84. what is the measure of the other two angles of the triangle?

Answer 1

84+x=140
x=140-84
x=56
84+56+y=180
140+y=180
y.=40

Answer 2

hlo

your answer..

as , the sum of two interior angle is equal to exterior angle

84 + x = 140
x = 140 - 84
x = 56°

now , two interior angles are 84° and 56°

sum of angle of a triangle is 180°

84 + 56 + x = 180
140 + x = 180
x = 40°


so , other two angles are 56° and 40°✔✔

hope it helps...
