Question

For parallelogram LMNO, if angle L=4x-25 and angle N=3x+18, find angle M

Answer 1

L=N (because opposite angle of parllalogram is euqal)

4X-25= 3X+18
X =43

there for angle N=3×43+18
N=147

Now we know that the sum of the corresponding angle of a parllalogram is 180
N+M=180
M=180-147

M=33
