Question

What is m angle 1 in this parallelogram
20o
60o
80o
100o<--

Answer 1

well the 2 angles are supplementary

3x + 20 + 5m = 180

or

8m + 20 = 180

solve for m

then angle 1 = 3m + 20

since opposite angles of a parallelogram are equal...

hope this helps

Answer 2

It doesn't really it just confused me more I'm thinking its twenty now

Answer 3

nope... solve the equation for m...

well m is 20....

now substitute it into 3m + 20

what do you get..?

Answer 4

80

Answer 5

yes... so thats the measure of 1...
