71/5=14.2
Answer:
The answer is 22.
Step-by-step explanation:
1) Replace the x with 17, and the y with 12.
2) 2(17) - 12
3) 2x17 = 34
4) 34 - 12 = 22
Answer: a = 23 ft.
Reasoning:
The question asks for the value of the leg a, given the tangent of the opposite angle and the length of the adjacent-leg, b.
The ratio that relates the three parameters is:
tan(A) = opposite-leg / adjacent-leg = a / b = a / 23 ft
Solve for a, wich is the unknown:
a = 23ft * tan(A) = 23ft * 1.0 = 23 ft
Answer: 23 ft.
