JKLM is a parallelogram, m∠K = (3x+20)° and m∠M = (7x)°. Find the value of ‘x’ and m∠M.

Answer: x=5 m<M =35 degrees
Step-by-step explanation:
In a parallelogram those two angles will be congruent. Set the two expression equal to each other and solve for x. Then plug x into the expression “7x” to find the measure of <M.
