Answer:
base = 17.71 ft
height = 9.71ft
Step-by-step explanation:
Since we are not given the base and heigh directly, to answer this question we need two equations: (1) one to express the area (A) of a triangle, and (2) one describing the fact that height (h) and the base (b) lengths are related. Setting up and solving the system of these two equations for base leads to a quadratic equation:
![\frac{1}{2}b\cdot h =A=86 ft^2\\h = b-8\\\rightarrow\\\frac{1}{2}b(b-8)=\frac{1}{2}b^2-4b=86\\\frac{1}{2}b^2-4b-86=0\implies\\b=4\pm2\sqrt{47}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Db%5Ccdot%20h%20%3DA%3D86%20ft%5E2%5C%5Ch%20%3D%20b-8%5C%5C%5Crightarrow%5C%5C%5Cfrac%7B1%7D%7B2%7Db%28b-8%29%3D%5Cfrac%7B1%7D%7B2%7Db%5E2-4b%3D86%5C%5C%5Cfrac%7B1%7D%7B2%7Db%5E2-4b-86%3D0%5Cimplies%5C%5Cb%3D4%5Cpm2%5Csqrt%7B47%7D)
which has two solutions but one is negative, i.e., not applicable. The good solution for base is
.
Since we know the height is 8 ft less than the base, the height must be 9.71ft
