Question

in the angle XYZ given below write the name of equal sides and determine the third angle?​

Answer 1

Answer:

Y = 100°

Isosceles Triangle on the basis of sides

Obtuse-angled Triangle on the basis of Angles

Step-by-step explanation:

Sum of all the angles of a Triangle = 180°

Two angles are given and they are = 40° and 40°

Let the third angle be x

40° + 40° + x = 180°

80° + x = 180°

x = 180°-80°

x ° 100°

The third angle (y) equals to 100°
