Sin A = opposite / hypotenuse
If angle A is in the first quadrant, that means both x and y coordinate are positive.
Now you can draw triangle. Since sinA = 1/3, opposite side may be 1, so then hypotenuse side must be 3.
Now you can use Pythagorean Theorem to solve for the length of adjacent side:
a² + b² = c²
1 + b² = 9
b² = 8
b = 2√2
So adjacent side is 2√2.
So now we can solve for cosA:
cosA = adjacent / hypotenuse = 2√2 / 3
Final answer: 2√2 / 3

i dont really ave an explanation a just used a calculator
Answer:
C) (5,0)
Step-by-step explanation:
1. The correct answer is C) because when we move five units to right from the origin, and zero units up, we end up at point H!
14.2 - 2.2 - 1
12 -1
