I want the answer please!

x = 38 degrees.

The angle marked 2x-1  =75 degrees

Step-by-step explanation:

the opposite angles of a parallelogram are equal.

so:

2x -1 = 75

2x = 76

x = 38

Hope this helps

x=38

Step-by-step explanation:

A quadrilateral's interior angles add up to 360°

In a parallelogram, the sides diagonal from it are the same angle measure. This mean that ∠K is 105° and ∠L is 75°. From this, we get:

2x-1=75

Add 1 to both sides

2x=76

Divide both sides by 2

x=38

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
