Answer:
Last option is the correct answer.
Step-by-step explanation:
Since, 61° + 57° + 61° = 179° < 180°
Therefore,
cannot be the measurements of triangle ABC.
by pythagorean formula, the last side is √(61)
by cos rule
cos A
A = 39.81
Answer: 15
12^2 + 9^2 = 225
square root of 225 = 15
His new balance would be $302
f(0) means x = 0
so when x = 0, y = -5
and when x = 4, f(4) is also equal -5 (y = -5)
so f(0) = f(4) = -5
Answer
D) f(4)
