Christine wants to measure the width of a river. She marks off two right triangles, as shown in the figure. The base of the larger triangle has a length of 55m, and the base of the smaller triangle has a length of 31m. The height of the smaller triangle is 20.2m. How wide is the river? Round your answer to the nearest meter.

boat which has a speed of 5 km/hr in still water crosses a river of width 1 km along the shortest possible path in 15 minutes. Then what is the velocity of the river water in km/hr ?

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 triangle has lengths the ratio of 3 : 6 : 5. If the longest side is 30 cm, what is the length of the shortest side?

Two triangles are similar. One has sides of 8 m, 5 m, and 6 m. If the longest side of the second triangle is 5 m, what are the length of the shortest side of the second triangle? (Answer to two decimal places.)
