In the image m || n || p. Given ∠10 = 2x + 70

∠7 = 5x – 20

Find m∠3.

Given:

In the given figure .

To find:

The .

Solution:

If a transversal line intersect two parallel lines, then the alternate exterior angles are equal.

         (Alternate exterior angle)

Divide both sides by 3.

Now,

              (Corresponding angles)

Therefore, the measure of angle 3 is 130 degrees.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
