Answer: B is 11 feet tall
A=x+1 since A is one more than B
C=x+1/2 since C is one half more than B
B=x since B is just B
A+B+C=34.5
x+1+x+x+1/2=34.5
3x+1.5=34.5
3x=33
x=11
B is 11 feet tall
y-y1 = m(x-x1)
where: x1 = 1 y1 = 8 (given point (1,8) and m = -3
y - (8) = -3 (x - (1))
y - 8 = -3 (x-1)
y- 8 = -3x +1
