## Questions

### Subject: Trigonometry

Imagine a ladder is leaning against a building. The bottom of the ladder rests on the ground 12 feet from the building and the ladder is 28 feet long. What is the measure of the angle the ladder makes with the ground?

Since we are looking for the measure of the angle the ladder makes with the ground, and we have the adjacent and hypotenuse measurements, we can use the cosine trig function cos(x) = adjacent/hypotenuse. cos(x) = 12/28 x = arccos(12/28) x = 64.6 degrees

### Subject: Mechanical Engineering

While there are many different technical subjects taught within Mechanical Engineering, companies usually require many other skills such as project management, team leading, and time management when looking to hire. How could you develop these types of skills while obtaining your degree in Mechanical Engineering?

This requires a student to stretch themselves beyond simply the required curriculum by getting involved in clubs, organizations, honor societies, or courses not required by the degree (if possible).

### Subject: Algebra

If 2x-5=4x+11, what does |4x| equal?

Since 2x-5=4x+11, we solve for x, giving us x=-8. By plugging x=-8 into the equation |4x|, we would multiply the value of x by 4 which would give us -32. The vertical lines around the equation |4x| show us we need to take the absolute value of -32, which is the numerical distance -32 is from 0. This distance is 32 so the answer is 32.
