Choose each angle measure that is one of the angles of these similar triangles. Select all that apply. Two triangles intersect at a single vertex. The vertices were the triangles intersect are labeled left parenthesis 4 x plus 7 right parenthesis degrees in the left triangle and left parenthesis 5 x minus 10 right parenthesis degrees in the triangle on the right. The lower angle in the left triangle measures 3 x degrees and the upper angle in the triangle on the right measures left parenthesi 4 x minus 14 right parenthesis degrees.

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
