HEY THERE FAM.
THE CORRECT ANSWER IS....<span> D.(4x-7x)+11</span>
Step-by-step explanation:
Surface area of a square pyramid is the area of the square base plus the area of the four triangles made from the base and the slant height.
SA = s² + 4(sh/2)
which reduces to:
SA = s² + 2sh
You are told that s = 11 and SA = 319. You can now solve for h:
319 = 11² + 2(11)h
319 = 121 + 22h
198 = 22h
h = 9 ft (answer C)
I hope it's helpful!!
The solutions are where these two functions intersect, that is, at x = -4 and x = -6. The answer is C.
As the building is 88 meters along the around and the shadow makes with a straight line of 32 degrees it would equal 55 meters high.
