Answer:
The sine = 0.2724 and the cosine = -0.9615 to 4 decimal places.
Step-by-step explanation:
The point (-7,2) is in the second quadrant .
The sine is positive and the cosine is negative,.
The hypotenuse of the triangle in the second quadrant = √((-7)^2 + 2^2)
= √53 ( by Pythagoras), the opposite side = 2 and the adjacent side = -7.
So the sine of the angle is 2 /√53 and the cosine is -7/√53.
or 0.2724 and -0.9615 to 4 decimal places.
