I NEED HELP PLS this is due today, thank u

a. (7x)+(x-12)=180

b.

m<1=168

m<2=

Step-by-step explanation:

We know that angle 1 and angle 2 add up to 180 degrees. We also know their measures, so we can plug them in.

m<1+m<2=180

(7x)+(x-12)=180

8x-12=180

8x=192

x=24

Now let's plug it in to solve for the measures.

m<1=7x

m<1=7(24)

m<1=168

m<2=x-12

m<2=24-12

m<2=12

We know this is correct because 12+168=180.

if you mean

then it's c. 8, -7/3

but if you mean

then it is

answer is 144
