I don't think it can be reduced anymore.
So firstly, factor out h on the left side: 
Next, divide both sides by h: 
Lastly, subtract both sides by b and your answer will be 
D) 34/5 because 6(5) = 30 30+4=34 , so its 34/5
Answer:
15.09
Step-by-step explanation:
with reference angle 28°
perpendicular (p) = 8
base (b) = x
Now
tan 28° = p / b
0.53 = 8 / x
x = 8 / 0.53
x = 15.09
