To find the length of the light pole you'll have to use the sine ratio.
sin 30 = x/43
43 (sin 30) = x
21.5 = x

Answer:
Step-by-step explanation:
y + 5 = 8(x - 0)
y + 5 = 8x - 0
y = 8x - 5
1. H=4
W=8
2. L=27
W=21
1. 160÷5=32
1/2 of 8 is 4
8×4=32

2. 2×6=12
96-12=84
84÷4=21
21+6=27 (the length)
21= (the Width)
