The side of a tent makes an angle of 65° to the ground. if a boy who is 1.1 m tall stands inside the tent with his head touching the tent's peak, how long is the fabric that makes up the side of the tent? a. 0.6 m b. 0.9 m c. 1.1 m d. 1.2 m

D. 1.2 m

Explanation:

According to the description, the boy, the side of the tent and the ground form a right triangle, which means we can solve this problem with a trigonometric function.

If in this right triangle the boy (whose length is ) and the ground are the sides of the triangle and the fabric that makes a angle with ground is the hypotenuse, we can use the function sine:

Finally:

This is the length of the fabric
