Answer:
375.3 ft
Explanation:
What we need to do first is divide 175 by the sine of 25°.
175/sin(25°)
175/0.422618
175/1 * 500000/211309
25/1 * 500000/30187
12500000/30187
414.085534 = length of hypotenuse.
Now, find the square root of the difference between c² & a².
b = √414.09² - 175²
b = √171470.528 - 30625
b = √140845.528
b = 375.293922
b ≈ 375.3
