Xavier uses a 20-foot ladder to paint a section of his house, and he rests it on a ledge that is 16 feet off the ground, as shown in the diagram. solve for angle . show your work.

The angle which ladder makes with the ground is 53.13

Step-by-step explanation:

Given as :

The length of the ladder = 20 foot

The length of the ledge = 16 feet

The ladder makes an angle Ф with the ground

From figure, in triangle CAB

So, Sin angle =

I.e Sin Ф =  

Or,  Sin Ф =

or,   Sin Ф =

or, Ф =

∴   Ф = 53.13

Hence The angle which ladder makes with the ground is 53.13 Answer

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

step-by-step explanation:

their are no angles. sorry cant .
