Which ray is a bisector of angle A B C? Select one:
A. stack B C with rightwards arrow on top
B. stack B D with rightwards arrow on top
C. stack B A with rightwards arrow on top
D. stack B F with rightwards arrow on top

What is GH?

Select one:
A. 5
B. 10
C. 15
D. 25

===================================================

Explanations:

Use a marker/pen of a different color to highlight angle ABC so its easier to see. Check out the diagram below. The only ray in the interior of this angle is ray BD.  The bisector must always be in the interior. The angle markers for angle ABD and DBC are the same indicating they are the same measure; therefore, ray BD bisects angle ABC.

------------------------

Segments IG and GH are the same length because they share the same single tickmark. Their lengths are shown as 3x and 5x-10. Set the algebraic expressions equal to one another. Solve for x. Then use this x value to find GH

IG = GH

3x = 5x-10

3x-5x = -10

-2x = -10

x = -10/(-2)

x = 5

GH = 5x-10

GH = 5*5-10

GH = 25-10

GH = 15

note that IG = 3x = 3*5 = 15 as well

the correct answer is a.) bc< mn 5 stars if this you : )

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
