Answer 1

13.2 is the answer

DO NOT PUT 13.21 OR YOU WILL GET IT WRONG, I TOOK THIS QUIZ AND PUT 13.21 AND I WAS WRONG, THE CORRECT ANSWER IS 13.2

Answer 2

we have been given a right angled triangle, hypotenuse is known, and angle has been given. we need to find the adjacent side to the angle.

we use trigonometry ratios.
the ratio where we relate the hypotenuse and adjacent side is the cosine.
cos θ = adjacent side / hypotenuse
where θ = 39°
hypotenuse - 17 m
adjacent side - x
we need to solve for x

cos 39° = x / 17
cos 39° = 0.77
0.7771 = x/17
x = 0.7771 x 17
x = 13.21 m
distance from Roman's feet to the base of the pole is 13.21
