Question

and exterior angle of a triangle in 130 degree and its interior opposite angles are in the ratio 7 ratio 6 find the measure of each angles of the triangle

preet where from u​

Answer 1

Answer:

A triangle has three sides.

So it's exterior angle is 130 degree

The interior opposite side or the interior side is 7 ratio and 6 ratio..

Let find it :

Step-by-step explanation:

So first we should know is the sum of all interior sides is equal to the exterior angles.

So the angles let it be 7x and 6x

The angles = 180-130 = 50

7x + 6x + 50 = 180

13x = 180 - 50 = 130

2x = 130/2 = 65

3x = 130/3 = 43

So the angles are founded,

It's 65 degree and 43 degree

Answer 2

Step-by-step explanation:

Let y and y be the interior opposite angles.

∴130

o

=x+x Exterior angle property

⇒2x=130

o

⇒x=65

o

Therefore, each interior angle if of 65
