Answer:
x = 20
B = 92
C = 40
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
A+B+C = 180
48+6x-28+2x = 180
Combine like terms
20+8x =180
Subtract 20 from each side
20+8x-20 = 180-20
8x = 160
Divide each side by 8
8x/8 = 160/8
x = 20
Then we need to find angle B
B = 6x-28 = 6(20)-28 = 120-28 =92
Then we need to find angle C
C = 2x = 2(20) = 40
Answer:
x=20
m>B=92
m>C=40
Step-by-step explanation:
the angles in a triangle add up to 180
48+6x-28+2x=180
6x+2x-28=132
6x+2x=160
8x=160
x=20
6(20)-28
120-28=92
2(20)=40
