DONT ANSWER IF YOU DONT KNOW PLEASE!!

80   i hope this helps!   :)

Step-by-step explanation:

we have 80 and 25 out of a 180 line

lets subtract 80 from 180 to get 100.

then subtract 25 from 100 to get 75

so the x is equal to 75 degrees

180 - 75 = 105

105 - 25 = 80

so the measure of angle AGC is 80 degrees

srry idk

step-by-step explanation:

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
