if ray XV is parallel to line LR, measurement of angle 2 = 2n-4 and measurement of angle 3 = n+1. find the value of n.

I solved the question using the condition that ray XV is perpendicular (not parallel) to line LR, as shown in the image.

n=31°

Step-by-step explanation:

If ray XV is perpendicular to line LR, then the four angles they form are equal to 90°.

We can see that angles 2 and 3 form a right angle, or:

We are also given that:

Substituting (get rid of the units):

Joining like terms:

Adding 3:

Solving:

n=31°
