Hong wants to measure the width of a river. He marks off two right triangles, as shown in the figure. The base of the larger triangle has a length of 63m, and the base of the smaller triangle has a length of 35m. The height of the smaller triangle is 20.2m. How wide is the river? Round your answer to the nearest meter.

A surveyor measures the distance across a river that flows straight north by the following method. Starting directly across from a tree on the opposite bank, the surveyor walks 100 m along the river to establish a baseline. She then sights across to the tree and reads that the angle from the baseline to the tree is 35°35° . How wide is the river?

A surveyor is trying to measure the distance BC across a river. From point B, directly across from point C, he walks along the bank to point A from which he sites C at an angle of 45o. If the distance AB is 120 yards, how far is it across the river?

A boat is crossing a wide river flowing at 8 km/hr. from west to east. The landing port is exactly the opposite of the starting point on the south bank of the river. If the boat moves at 10 km/hr. to cross the river and crosses it in 1/2 hr., what is the width of the river?
