Question

Find the value of x if the area of the triangle is 280 in squared?

Answer 1

area of a triangle = \(\bf \cfrac{1}{2} \times base \times height\)

Answer 2

so we know the area is 280, we know the base is 70 inches, thus \(\bf Area = \cfrac{1}{2} \times base \times height\\
280 = \cfrac{1}{2} \times 76 \times height\)

solve for "height"

Answer 3

I got 7.37 for height, :/ but that's not one of the options

Answer 4

ohh smokes, yes, I put 76, but it's 70

Answer 5

\(\bf Area = \cfrac{1}{2} \times base \times height\\
280 = \cfrac{1}{2} \times 70 \times height\)
