Question

if the verical angle of an isosceles triangle is 1000 then find the neasures of its base angles

Answer 1

Let, the measure of each of the base angles be x°.

Applying Angle-Sum Property of triangles,

x°+x°+100°=180°

=>2x°=180°-100°

=>2x°=80°

=>x°=40°

Therefore, the measure of each of the base angles=x°=40°
