Question

Find the area of an isosceles triangle having perimeter 36cm and if one of equal sides is 10 cm​

Answer 1

Answer:

85°.

Step-by-step explanation:

If the triangle is isosceles, than 2 of its sides will be equal. We are given one of its sides is 10 cm, then

let the other two side be x cm.

A/Q,

10 + x + x = 180. ( Angle sum property of a triangle)

10 + 2x. = 180

2x. =. 170

x. =. 85

Hence, the measure of both of the angles are 85°.
