A zoo is building a new giraffe exhibit and needs to fence an outdoor triangular area, with the barn forming one side of the triangle. The maintenance department has only 128ft of fencing in stock. If one of the sides of outdoor pen is 77ft and angle makes with barn is 72 degrees, does the zoo need to order more fencing?

step-by-step explanation:

i think that you should ask google for the answer to that problem because if we don't know it google does

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
