Which is the right answer?
2 answers:
Answer is (-2,1) the second choice
Reason
Remember, a function can only assign an input value to one output value. If you see the same x-value with more than one y-value, it’s not a function
There are two -2 x values (-2,1) and (-2,-3) so one has to go
The choices say to eliminate ( -2, 1)
There is also a vertical line test, if a vertical line goes over a point more than once, it is not a function.

Answer:
B. 34.90°
Step-by-step explanation:
✔️First, find GF using Trigonometric function:
Reference angle = 58°
Adjacent length = GF
Hypotenuse = 6 cm
Apply CAH, thus:
Cos 58 = Adj/Hyp
Cos 58 = GF/6
GF = 6*Cos 58
GF = 3.17951558 ≈ 3.18 cm
✔️Find angle K using the Sine Rule:
Substitute
Multiply both sides by 3.18
K = 34.8618741° ≈ 34.90°
