determine the numerical measure of each angle of parallelogram x+40 3x-20

Question

x=
m/_M=
m/_I=
m/_L=
m/_K=

Answer 1

you don't say whether the values given are opposite or adjacent angles.

So, you have one of two cases:

x+40 = 3x-20
x+40 + 3x-20 = 180

Pick the one you want, solve for x, and then you can answer the questions.
