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 :)

i am unable to solve this problem

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
