Jaxon wants to know the length of a bridge (in meters) for his school project. He bought a metric tape measure with him. Unfortunately, he bought a 20-meter metric tape measure and it wasn't enough to measure the bridge from points A to B without including the bridge, which is unfortunately arched and would measure greater than the length of the bridge itself. So, he decided to go to center (as it is also the highest point) of the bridge and used the metric tape to measure the height of the bridge which is 28.5 meters. He, then, installed an online protractor in his phone and measured the angle of depression from the center of the bridge to the point B which is 60 degrees. Using the new information Jaxon gathered, calculate the length of the bridge (AB), and the hypothenuse. A 16.45 60° Afterwards, check the value of (AB) using sine, cosine and tangent.
