1). a = 9.42 m

2). b = 6.37 m

3). c = 4.48 m

Step-by-step explanation:

In the figure attached,

By applying tangent rule in triangle ADE,

tan47 =

c =

c =

c = 4.476

c ≈ 4.48 m

Now we apply the same rule in triangle ACE,

tan37° =

b =

b =

b = 6.37 m

Now apply the tangent in triangle ABE,

tan27° =

a =

a =

a = 9.42 m

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

10 b/c 5*2 =10
