One of the equal angles of an isosceles triangle is 45 degree find the measure of other two angles

Answer»

Step-by-step explanation:

Given: TWO equal ANGLE of isosceles triangle=45°

let the measure of THIRD angle be X

WKT; the angle sum PROPERTY of a triangle=180°

55°+55°+X=180°

110°+X=180°

X=180°-110°

X=90°

The measure of other two angles is 55°and 90°
