A special kind of triangle is a right triangle whose definite characteristic is having a 90° angle. It is also special because there are derived trigonometric formulas/identities that can be applied to it. A right triangle has three sides: hypotenuse, adjacent side and opposite side. The hypotenuse is the longest side of the right triangle. You can determine this visually, if not, quantitatively. The other sides are with respect to a given angle.
For the problem, it might have asked for the opposite side or the hypotenuse. We use the cosine function to find the hypotenuse:
cos 58° = adjacent/hypotenuse = 4/hypotenuse
hypotenuse = 7.55 units
Then, we use the tangent function to find the opposite side.
tan 58° = opposite/adjacent = opposite/4
opposite = 6.4 units
Correct option:
d. 1.64
<h2>
Explanation:</h2>
An object is launched vertically upward from a 25 foot platform and is modeled by the following function:
So this is the equation of a parabola because the object is a projectile so it follows the Projectile Motion.
The object fall back to the ground when 
so:
Since time can't be negative, we only choose the positive value. therefore:
<em>The object fall back to the ground after 1.64 seconds</em>
