Question

Angle 1 and angle 2 are supplementary angles. m<1 is 4y + 7, and m<2 is Sy + 4. Find m<2.

Answer 1

Explanation:

First, we should define supplementary angles.

Supplementary angles are angles that add up to 180 degrees.

Since 1 and 2 are supplementary and we know their values, we just set them equal to 180 degrees

(

4

y

+

7

)

+

(

9

y

+

4

)

=

180

Now just solve for one variable

13

y

+

11

=

180

13

y

=

169

y

=

13

Now the question asks for m<2, which is

9

y

+

4

So we just plug in

9

⋅

13

+

4

=

121

So m<2 is 121
