Question

if the vertical angle of isosceles triangle is 40 degree then find the measure of other two angles​

Answer 1

$\huge\mathcal\pink{Answer:-}$

Sum of the 3 angles in a triangle is 180°

Angle at vertex is 40°

180-40=140°

The other 2 angles in isosceles triangle I are eqal

140/2 =70

The other 2 angles of isoceless triangle are 70 and 70

Hence required answer:-70,70
