so the basic formula for this d = rt
where d is the distance , r is the speed and t
is time
3800 – 120t = 520 + 40t ( this is the altitude
of each plane are equal)
Solve for t
T = 20.5 min time it takes for the planes to be
at the same altitude
3800 – 120(20.5) = 1340 ft

140 degrees, solve for the interior angle of LMK which can be found by 180-90-50 so now we know this is 40. However we need the other angle( KMU) that is supplemental with it, so 180-40 gives you 140 which is your final answer.
140 degrees
The following figures are similar. They are both the same shape, One is just bigger.
The 3 inside angles of a triangle need to equal 180 degrees.
You are given 28 for one.
The second on is adding 58 + 77 = 135 degrees.
X = 180 - 28 - 135 = 17 degrees
