Answer:
60 degrees
Step-by-step explanation:
Given is a parallelogram LMNO
Angles are given as 4r , 3t-1, 3s and 2t+10
Since in a parallelogram opposite sides are parallel, we have
sum of adjacent angles =180:
4r+2t+10 =180 ... i
Also opposite angles equal
Hence 3t-15 = 2t+10
t =25
Substitute this
in angle M = 3t-15
=3(25)-15
=60
