@Allison

Answer 5

I don't math either

Answer 6

lol ok

Answer 7

We have to use tangent because it's adjacent and opposite

Answer 8

@Vocaloid

Answer 9

good, so if tan(theta) = opposite/adjacent what would be the correct expression for the height of the lamppost?

Answer 10

A.

Answer 11

keep in mind:

the opposite side = AB

so tan(50) = AB/10

what do you get when you solve for AB?

Answer 12

11 feet?

Answer 13

keep in mind the answers are all in terms of tan or cos

tan(50) = AB/10

just multiply both sides by 10 and don't do anything else

Answer 14

500 lol

Answer 15

tan(50) = AB/10

notice how AB is being divided by 10

we multiply both sides by 10 to "undo" the division

so AB = 10*tan(50) = your solution.
