At a river the surveyor picks two spots, X and Y, on the same bank (side) of the river and a tree, C, on opposite bank. X=80 and Y=50 and XY=300', how wide is the river? (Remember distance is measured along perpendiculars) Thank you :)

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

inverse property is the answer
