In the diagram mz3= x+ 30 and mz4 =2x-80. What is the measure of angle 3?

Given:

Consider the below figure attached with this question.

and .

To find:

The measure of angle 3.

Solution:

From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.

We know that, vertically opposite angles are always equal. So,

Now,

Therefore, the measure of angle 3 is 140 degrees.

i belive those are the ones that are under 90 degreese.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:
