Remember that straight lines are 180°. For #1 angle 1 would be 40°, since 140°+40°=180°
A is the answer, the proportion RS/VU=2, the proportion of ST/UT=2, an angle S is equal to angle U, both 90 degrees. RS/VU, side, angle S = to angle U, angle and ST/UT, side.
A line graph. The amount of time to do those things relates more to a line graph
