Answer:

b = 7 $\sqrt{3}$

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for b

and the exact value

tan30° = $\frac{1}{\sqrt{3} }$ , thus

tan30° = $\frac{opposite}{adjacent}$ = $\frac{7}{b}$ and

$\frac{7}{b}$ = $\frac{1}{\sqrt{3} }$ ( cross- multiply )

b = 7 $\sqrt{3}$
