Question

Determine the value of “m” in the parallelogram below.

Answer 1

m= 170

Explanation:

Given that this is a parallelogram, we know that 70°+(m-60)° has to equal 180°. So, we can set it up like this: 180-70=(m-60) and solve from there. The next step: 110= (m-60). Then, isolate the variable (add 60 on both sides):110+60=m. So, m=170.

Answer 2

m = 170

Explanation:

The angles are supplementary so they add to 180 degrees

70 + m-60 = 180

Combine like terms

10 + m = 180

Subtract 10 from each side

10-10 +m = 180-10

m = 170
