Question

in fig, prove that angle x=angle a+angle b+angle c​

Answer 1

Answer:

130°

Step-by-step explanation:

It's a closed figure. There are 3 angles inside it. We know that a closed figures all angles sum up to 180°.

If,

Angle A = 40°

Angle B = 50°

Angle C = 40°

Then,

Angle X = 40° + 50°+ 40°

Angle X = 130°

(The measures of angles are not to scale)
