Question

Directions: Type your answer in the box.

The figure shows JN and KM intersecting at point L.
M.
N
3x
48°
What value of x proves JK || MN?
X+42°
K

Answer 1

x = 21

Explanation:

Based on the behavior of linear angles, the blank angle across from the 48 degree angle shown in the image is also 48 degrees.

To prove the two lines are parallel, set the two angles given in the corners equal to each other:

x + 42 = 3x

42 = 2x

x = 21
