Question

if x°,30°,90° are interior angle of a triangle then find the value of x°​

Answer 1

x=60°

Step-by-step explanation:

Using angle sum property of triangle,

x°+30°+90°=180°

x°+120°=180°

x°=180°-120°

x°=60°

Answer 2

In a triangle sum of all angles is 180°

x°+30°+90°=180°

x°+120°=180°

x°=180-120

x°=60°
