Question

The two interior opposite angle of a triangle are 60° and 80° . find the measure of exterior angle.
plz tell me answer plz tell. me answer before 8 :30 ​

Answer 1

Step-by-step explanation:

Given that two interior opposite angles of the exterior angle of a triangle are 60 degrees and 80 degrees. The Measure of the exterior angle is equal to the sum of two interior opposite angles. Hence, the measure of the exterior angle will be 60°+80° = 140°.

Answer 2

Given :-

Two interior opposite angles are 60° and 80° .

To Find :-

The measure of exterior angle = ?

Solution :-

As we now that,

Exterior angle is the sum of two opposite interior angles

Therefore,

60 + 80 = 140°

Exterior angle = 140°

Some more info :-

• Area of triangle = 1/2 * Base * Height

• Perimeter of triangle = Side + Side + Side

• Angle Sum property

Angle 1 + Angle 2 + Angle 3 = 180°
