Question

the exterior angle of triangle is 110 and one of the interior opposite angle is 35 find the other two angles of the triangle

Answer 1

since we all know that the sum of two opposite interior angle = to exterior angle therefore
let another interior angle be x then
35+x=110
x=110-35
x=75

Answer 2

exterior angle = Sum of interior opposite sides
110= 35 +x
x= 110-35
x= 75

now we got the two angles one is 35 and other is 75
so 35 +75+x=180 (angle sum property )
110+x=180
x=180-110
x=70
therefore the angles of the triangle are 35 75 and 70
hope it help you
