Question

If mAngle3 = 29°, what is mAngle4?

Answer 1

its 151°

Explanation:

Answer 2

Please consider the attached graph.

We have been given that measure of angle 3 is 29°. We are asked to find the measure of angle 4.

Upon looking at our diagram, we can see that angle 3 and angle 4 are linear angles.

We know that linear angles add up-to 180 degrees, so the sum of measure of angle 3 and angle 4 will be 180 degrees.

`m\angle 3+m\angle 4=180^(\circ)`

`29^(\circ)+m\angle 4=180^(\circ)`

`29^(\circ)-29^(\circ)+m\angle 4=180^(\circ)-29^(\circ)`

`m\angle 4=151^(\circ)`

Therefore, the measure of angle 4 is 151 degrees.
