Which is the angle of elevation from Kelley to the top of the waterfall? ∠7 ∠5 ∠8 ∠6

∠6

Step-by-step explanation:

The angle of elevation is the angle between an horizontal line and the line from the object to the observers eyes. The line from the object is above the horizontal line. The angle of elevation denotes the angle from the horizontal upward.  

The first picture below is where your question emanated .The second picture describes the angle of elevation. The angle of elevation from kelley to the top of the waterfall is ∠6.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
