stiks02 [169]
ANSWER: 25x+300=1000

EXPLANATION: $25 is how much each artwork is worth so you multiply that by how many artworks needed to make 1000, but since you don’t know how many you need you put an x. You’ve already made $300, so you add that to 25x so you get 25x+300 and then finally because you need your outcome to be 1000 you put that as what the equation should equal to and you should get 25x+300=1000.

Answer: 113.0 ft (bottom right corner)

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

Explanation:

The triangle has a horizontal leg of 220 ft and a vertical leg of x ft. We'll use the tangent rule to connect the opposite side and adjacent side

opposite side = x
adjacent side = 220
this is with the reference angle shown in the diagram

So,
tan(angle) = opposite/adjacent
tan(26) = x/220
220*tan(26) = x
x = 220*tan(26)
x = 107.301169 ... see note below
x = 107.3

Now that we know the approximate value of x, we add on 5.7 to get
x+5.7 = 107.3+5.7 = 113.0

note: make sure your calculator is in degree mode. The value is approximate to 6 decimal places
