The sine of any acute angle is equal to the cosine of its complement. Meanwhile, the cosine of any acute angle is equal to the sine of its complement. Sine and cosines are called "cofunctions".
Answer:
h(t) = -4.9(t - 3)^2 + 50.
Step-by-step explanation:
h(t) = -4.9t^2 + 29.4t + 5.9
h(t) = -4.9(t^2 - 6t) + 5.9 Complete the square on t^2 - 6t:
h(t) = -4.9[ (t - 3)^2 - 9] + 5.9
h(t) = -4.9(t - 3)^2 + 44.1 + 5.9
h(t) = -4.9(t - 3)^2 + 50

Answer:
![\frac{9\sqrt{3} }{2}](https://tex.z-dn.net/?f=%5Cfrac%7B9%5Csqrt%7B3%7D%20%7D%7B2%7D)
Step-by-step explanation:
since the triangle is a 30-60-90 triangle:
√3 : 2 = x : 9
=> 2x = 9 √3
=> x = ![\frac{9\sqrt{3} }{2}](https://tex.z-dn.net/?f=%5Cfrac%7B9%5Csqrt%7B3%7D%20%7D%7B2%7D)
