to measure the height of a castle surrounded by a moat, Xena stands at the edge of the moat and measures the angle of elevation at the top of the castle to be 82. when she backs away 120 feet, the angle of elevation is 68. (a) how tall is the castle? (b) how wide is the moat?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

i honestly dont know
