What is the length of ? round to the nearest tenth. 9.7 m 10.4 m 37.3 m 38.6 m
THIS IS THE BEST ANSWER 👇
Using basic trigonometry we can write an equation in COS.
Taking 75 ° as the angle, it is given the adjacent side and we have to get hypotherapy (x). Hence, we use cosine.
We know , so that we can write,
The length of x, rounded to one decimal place, is 38.6 meters. The fourth option is correct.
