Option A:
a = 23 ft
Solution:
The given triangle is right triangle.
The value of tan A = 1.0
b = 23 ft
Using trigonometric formula,


Substitute the value of tan A and b.

Do cross multiplication, we get
1.0 × 23 = a
23 = a
Switch the sides
a = 23 ft
The length of a is 23 ft.
Hence option A is the correct answer.
Answer: twenty-three feet
Step-by-step explanation:
We already have some givens. It's right triangle, the value of tan is A = 1.0 and b = 23 ft. So use the formula tanθ=opposite/adjacent.
1=a/23, now use cross multiplication.
1*23=a
23=a
a=23 feet
