Ultimately, you want the <em>variable</em> p on one side of the equals sign, and the <em>value</em> of p on the other.
First, get rid of the parenthesis by <em>distributing.
</em>There is an invisible -1 in front of the first and last set of parenthesis, and a one times any number is the number itself, so you are essentially distributing the negative sign. <em> </em>So you have: 2-4p-3 = -3p-6-2p-3 <em> </em>Next, <em>Combine like terms. </em> Can you take it from there?<em>
The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.
Step-by-step explanation:
You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x
