Question

An exterior angle of a triangle is 170 ⁰ and one of its interior opposite is 25 ⁰ . The measure of the other interior opposite angle is ​

Answer 1

Step-by-step explanation:

We know sum of opposite interior angles is equal to exterior angle

therefore,

y+25=170

y=170-25

y=145°

Now,

we know sum of all the angles of a triangle is 180°

x+145+25=180

x=180-170=10°

or

170+x=180 (linear angles)

x=10°
