Angle one and angle two are supplementary angles angle one equals x -39 and angle two equals x +61 find the measure of each angle

140 and 40

Step-by-step explanation:

The sum of supplementary angles  is   180

x-39 + x +61 = 180

2x+22 = 180

2x= 158

x=79

79-39=40

79+61=140

40 +140 = 180

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
