Question

in a triangles , find the third angle whin two given angle
30° , 60'​

Answer 1

Answer:

90°

Explanation:

let the third side be x°

by angle sum property of a triangle

60°+30°+x=180°

x=180-90

x=90°

Answer 2

heya mate!!! lets do it...

Do u recall Angle sum property

angle a + b + c = 180

so here,

a = 30

b = 60

c = ?

equation will be =  

30 + 60 + ? = 180

90  +   ? = 180

? = 180 - 90

? = 90

therefore third angle will be 90°

Hope it helps u alot...
