Ответ:
18 feet
Step-by-step explanation:
Well, it is a right triangle question. So, let us first define what is tangent in a right triangle. The tangent (tan) of right triangle is equal to length of opposite side divided by adjacent side. In our example, opposite side is given as 11 feet and tan(31.43)=0.611. So, adjacent side (the base of the tree from the swingset) = opposite side (distance from the ground to Emir's position)/tan(31.43). Hence, adjacent side (the base of the tree from the swingset) = 11/0.611=17.9997. If rounded to nearest foot, it is 18 feet.
