Use a geometric formula to solve the problem. a triangle has a height of 8 feet and an area of 48 square feet. find the base.

The formula for finding area of a triangle is:

The base is 8 feet. The area is 48 ft². Put that into the formula:

Remember that you have to multiply the base × height by , which is the same as dividing by 2. To find the height, you need to multiply the area by 2, instead of dividing.

That means the base × height is equal to 96. You already know the height. To find the base, divide the (base × height) by the height. The height is 8.

That means the base of the triangle is 12 ft

Base = 12

Height = 8

Put that into the formula:

✔

BASE = 12 ft

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?
