An unknown variable ..............
Answer:
D, E
Step-by-step explanation:
The applicable formula is ...
s = rθ
so, for θ = 1.5, the arc length is 1.5 times the radius. The true statements are ...
D) The length of the arc defined by the angle is 1.5 times longer than the radius.
E) The ratio of arc length to radius is 1.5.
Pair 2 is a reflection. If you rotated it it would be flipped, so that doesn’t make sense.

Because (4*3) + 3 = 15. Similary find the improper fraction for -2 1/2.
(15/4) / (-5/2) = -3/2
Convert -3/2 into a mixed fraction.
Therefore, -3/2 = -1 1/2.
By definition, the sine of an angle is given by:

Where,
C.O: opposite leg
h: hypotenuse
The hypotenuse is given by:

So, replacing values we have:

Rewriting we have:
Answer:
the sine value of this function is:
A)5 times square root 61 over 61
