Answer:
area = 779.4 cm²
Step-by-step explanation:
divide it into 6 equal equilateral triangles. Each corner of a triangle will be 60°.
tan 60° = 15/x
1.7321 = 15/x
x = 8.66 (this is one-half of the base of the triangle)
base = 17.32 cm
area of one triangle = 1/2(17.32)(15) = 129.9 cm²
129.9(6) = 779.4 cm² (because 6 triangles make up the hexagon)

Answer:
-117
Step-by-step explanation:
Plug -10 in every time you see "x". Then, I used a calculator to evaluate the function (find the answer). Then, I got -117.
Hope this helped :)
I’m pretty sure the answer would be 116
