Solve for x. enter your answer in the box. x = an equilateral triangle a b c. side b c is the base. sides a b, b c, and a c are equal. sides a b, b c, and a c are labeled with single tick marks. angle a is labeled as left parenthesis 2 y right parenthesis degrees, angle b is labeled left parenthesis 25 x minus 15 right parenthesis degrees.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

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
