a tree casts a 20-foot shadow. brian is 6 feet tall and casts a 4-foot shadow.
how tall is the tree?
a. 13 ft
b. 30 ft
c. 20 ft
d. 24 ft

Explanation:

Step1: Set up proportion

Let $h$ = tree height.
$$\frac{h}{20} = \frac{6}{4}$$

Step2: Solve for $h$

Multiply both sides by 20:
$$h = \frac{6}{4} \times 20$$

Step3: Calculate final value

Simplify the expression:
$$h = 6 \times 5 = 30$$

Answer:

B. 30 ft
