Question

If 130 is exterior and x and 50 are interior what is x

Answer 1

Answer:

Step-by-step explanation:

Given,

130° is exterior angle.

x° and 50° are interior angles

To Find :-

Value of x° .

Condition Required :-

Exterior angle equals to sum of two opposite interior angles.

Solution :-

$\implies 130^{\circ}=x^{\circ}+50^{\circ}$

$x^{\circ}=130^{\circ}-50^{\circ}$

$x^{\circ}=80^{\circ}$

∴ Value of x° = 80°

Know More :-

1) Sum of three angles in a triangle = 180°

2) Sum of linear pair of angles = 180°

3)Vertically opposite angles are equal

4)Corresponding angles are equal

5)Sum of alternative interior angles = 180°
