Question

solve the question number 7 plzzz

Answer 1

let the base angles be x , x.

given , vertex Angle = 50°

sum of all the interior angles of isosceles triangle

= 180°

x + x + 50° = 180°

2x = 130° => x = 65°

since, the base angles of isosceles triangle are equal.

so then x = x = 65°

Therefore,

base angles are x = 65° , x = 65°

Answer 2

let the base angle be x
vertex angel is 50 degree
angle sum property is 180 degree
A.T.Q
x+x+50 =180
2x+50=180
2x=180-50
2x=130
x= 130-2
x= 65
