3 lines are shown. A line with points M, H, K intersects with a line with points J, H, L at point H. Another line extends from point H to point N in between angle K, H, J. Angle M H L is (3 x + 20) degrees, angle K H N is (x + 25) degrees, and angle J H N is (x + 20) degrees. What is the measure of AngleJHN? 25° 45° 50° 95°

Answer:

Option B.

Explanation:

Given information: ∠MHL=(3x+20), ∠KHN=(x+25), and ∠JHN=(x+20).

We need to find the measure of ∠JHN.


\angle MHL=\angle JHK (Vertical opposite angles)


\angle MHL=\angle JHN+\angle KHN

Substitute the given values.


3x+20=(x+20)+(x+25)


3x+20=2x+45


3x-2x=45-20


x=25

The value of x is 25. So, the measure of ∠JHN is


\angle JHN=x+20=25+20=45

The measure of ∠JHN is 45°.

Therefore, the correct option is B.
