Question

Line r is parallel to line t. Find M 4. The diagram is not to scale

Answer 1

Explanation:

Hi there!

Given;

one angle (let be x)= 141°

Then;

141° + angle 3 = 180°. {being linear pair}

angle 3 = 180°-141°

angle 3 = 39°

Therefore, angle 3 is 39°.

Now; angle 3 = angle 4 = 39° {alternate angles are equal}

Therefore, the measure of angle 4 is 39°.

Hope it helps!

Answer 2

Answer:

M4=39°

Explanation:

M2=141° (corr angles, r//t)

M4=180°-141° (adj angles on a str line)

=39°
