Question

5.
Find the value of the unknown interior angle x in fig.​

Answer 1

➼ Answer ➼

Th Exterior Angle Property states that the sum of the two interior opposite angles equals to the Exterior Angles.

Hence,

1st Interior Opposite Angle = 50°

2nd Interior Opposite Angle = 70°

Exterior Angle = x°

50° + 70° = x°

120° = x°

Thus,

The value of x (Exterior Angle) equals to 120°.

Answer 2

REQUIRED ANSWER:

• X=120°

EXPLANATION:

Here's the concept of exterior angle of triangle is used, where we are given interior angles and we have to find exterior angle of triangle.

So let's apply exterior angle of triangle in the given triangle.

=> 50°+70°=x

=> 120°=x

Hence the value of x is 120°.
