7-41.

The triangles in the diagram at right are similar. Solve for . Show all work.

When two triangles are similar, the ratios of corresponding sides are equal.
You could use a proportion.

2 line segments intersect, with additional line segments to create 2 triangles, such that the 2 triangles share a common vertex, & the base of each is almost vertical. the triangles are labeled as follows: Left triangle: bottom angle, 1 tick mark, right angle, 2 tick marks, bottom side, 24, top side, 20. Right triangle: left angle, 2 tick marks, top angle, 1 tick mark, top side, x + 2, bottom side, x.
