x=20

m<B=92 degrees

m<C=40 degrees

Step-by-step explanation:

48+6x-28+2x=180

20+8x=180

8x=160

x=20

(6(20)-28)=92

2(20)=40

So, x=20, m<B=92 degrees and m<C=40 degrees

x = 20, angle B = 92, angle C = 40

Step-by-step explanation:

Solve for x.

48 + 6x - 28 + 2x = 180

8x + 20 = 180

8x = 160

x = 20

Angle B = 6(20) - 28 = 92

Angle C = 2(20) = 40

Proof: 48 + 92 + 40 = 180

Step-by-step explanation:

Because if she rode 10 mph means that she would ride 2.5 miles in 0.25 hours because if you divide 10 by 2.5 then you would get 0.25.
