A surveyor wishes to measure the width of a river. On her side of the river, she picks two points, A and B, that are 10 m apart. Then she identifies a point C on the opposite side of the river that is between A and B. She finds that A=45∘ and B =60∘.

What is the width of the river?

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
