Answer:
210°
Step-by-step explanation:
Given
sinΘ = -
Note taken the inverse sine of the positive value of the ratio, gives the related acute angle, that is
Θ = (
) = 30° ← related acute angle
Thus the required angle in the third quadrant is
Θ = 180° + 30° = 210°
Since h represents the height of the ball at any given time, t, let h = 25, such that the ball will be 25m high at t.
Now, we have 25 = 20t - 5t²
5t² - 20t + 25 = 0
t² - 4t + 5 = 0
Since the discriminant is less than zero, there are no solutions.
Hence, the ball will never be 25m high.
Now, we have 25 = 20t - 5t²
5t² - 20t + 25 = 0
t² - 4t + 5 = 0
Since the discriminant is less than zero, there are no solutions.
Hence, the ball will never be 25m high.
