An isosceles triangle has an angle that measures 140°. Which other angles could be in that isosceles triangle? Choose all that apply.

Every triangle is 180 degrees, so each other angle should have 20

are you an artist's daughter? cuz dang you a fine piece of art, girl.

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
