Erik is building a cubby bookshelf, that is, a book shelf divided into storage holes (cubbies) instead of shelves. He wants the height of the bookshelf to be x^2 - 6x - 27 and the width to be x^2 + 4x + 3. Each cubby hole in the bookshelf will have a height of x + 1 and width of x - 9. Step 1 of 3: Write a rational expression to determine how many cubbies high the book shelf will be. ​

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
