do you need the steps?
Answer:
m<1 = 105°
m<2 = 75°
very simple explanation:
a and b are perpendicular. line t intersects these perpendicular lines. the given 75° is, in short, an intersect of a line, which is 180°. 75-180=105. angles 1 and 2 are duplicates of what is shown
So it can be easier to solve your problem
Velocity
Formula wise:
1/2 x mass x velocity^2
