PLEASE HELP!!!!!!!!!!



<1 and <2 are supplementary. m<1 = 3x -4 and m<2 = 8x-14. Find the measure of each angle

Am<1 = 130° , m<2 = 50°
Bm<1 = 50° , m<2 = 130°
Cm<1 = 110° , m<2 = 70°
Dm<1 = 70° , m<2 = 110°

Verified Answer :

Blahblahblah1230

(3x-4)+(8x-14)= 180

11x-18=180
+18 +18
----------------

11x=198
x=18



m<1= 3(18)-4
m<1= 50

m<2=8(18)-14
m<2=130

Answer is B.

Answer:

The answer is the option b

\(m<1=50\°\), \(m<2=130\°\)

Step-by-step explanation:

we know that

If angle 1 and angle 2 are supplementary

then

their sum is equal to \(180\°\)

so

\((3x-4)\°+(8x-14)\°=180\°\) -------> solve for x

\((11x-18)\°=180\°\)

\(11x=180\°+18\°\)

\(x=198\°/11=18\°\)

\(m<1=(3x-4)\°=(3*18-4)\°=50\°\)

\(m<2=(8x-14)\°=(8*18-14)\°=130\°\)
