Which equation can be used to solve for b? a) tan(30°) = 5/b b) tan(30°) = b/5 c) tan(30°) = 10/b d) tan(30°) = b/10

In this exercise we want to calculate the value of angle B, so we have to:

Letter A

So knowing the tangent formula as:

Knowing some information given in the exercise such as:

So we have:

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
