Three trigonometric functions for a given angle are shown below. sin theta = -77/85, cos theta=36/85 tan theta=77/36 what are the coordinates of point (x, y) on the terminal ray of angle theta assuming that the values above were not simplified? a) (-77,-36) ,36) c) (-36,77) d) (36, -77)

The correct option is D.

Step-by-step explanation:

It is given that

The angle of terminal ray is θ, it means the angle between x-axis and terminal ray is θ.

Therefore the length of perpendicular is 77 and the base of the triangle is 36.

Since sinθ is negative and cosθ is positive, it means point must be lies on fourth quadrant because in fourth quadrant cosine in positive but sine is negative.

The point of terminal ray is (base, perpendicular) and the sign are used according to the quadrant.

Therefore the point of terminal ray is (36,-77) because in fourth quadrant x is positive but y is negative. Option D is correct.

this is false ^.^ lol

lol, i have been using this product for a while and the second half of the year for a lon and the first time in a long time ago that the government has not yet received enough votes to be a good the first place in the world to be able to do it in my world life, i
