Out of the given exercises, options A-C are all strength training exercises, while option D is an aerobic exercise. Therefore, the answer is dancing<span>.</span>
Note.... sin (-θ) = -sin(θ)
And tanθ =√15 / 15 = 1 / √15
So
-sin (θ) = -1/4 ⇒ sin (θ) = 1/4
And
tan (θ) = sin (θ) / cos(θ) rearrange as
cos (θ) = sin (θ) / tan (θ) = (1/4) / (1/ √15) = (1/4) * (√15 / 1) = √15 / 4 ⇒ C
Your Answer is B - Aerobic exercise is carried out for a sustained period of time.
