Question

Find the measure of angle KMU.​

Answer 1

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

Answer 2

50 + 90 = < KMU ( sum of exterior angle )

140 = < KMU
