Question

A triangle is 110 degree and one of the 110degree the interior opposite angle is 80degree find the other two angle of the triangle

Answer 1

Given ,
a triangle is 110 degree
and one of it's interior opposite angle is 80 .

we know that,
sum of the two interior opposite angles of a triangle is equal to the exterior angle of the triangle

80 +x = 110
x= 110-80
x=30
Know we know that ,
sum of the angles of a triangle=180
80+30+y=180
110+y=180
y=180-110 =70
