Question

Find the value of third angle:- angle =60° , angle 70° , angle = x°

Answer 1

Sum of angles in a triangle = 180°

↣ 60 + 70 + x = 180

↦ 130 + x = 180

↦ x = 180 - 130

↦ x = 50

Answer 2

Answer:

X=50°

There are 3 angles in a triangle.

Let triangle ABC

A=60°

B=70°

C=x°

Now,

A+B+C=180° ( angle sum pro. of triangle)

60°+70°+x°=180°

x°=180°-130°

x°=50°

so, the third angle is 50°
