Answer:
25.5
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships between angles and sides and trig functions in a right triangle. Here, the side adjacent and the side opposite the marked angle are also marked. That means the relevant trig relation is ...
Tan = Opposite/Adjacent
tan(49°) = x/(22.2 m)
Multiplying by the denominator, we get ...
x = (22.2 m)tan(49°) ≈ 25.5 m
The unknown side is about 25.5 meters.
Answer:
y = -1/2x^2 -5x -45/2
Step-by-step explanation:
Multiply it out and collect terms.
y = -1/2(x^2 +10x +25) -10 . . . . . expand the square
y = -1/2x^2 -5x -25/2 -20/2 . . . eliminate parentheses
y = -1/2x^2 -5x -45/2 . . . . . . . . collect terms
