How To Solve Algebraic Problems Involving Angles In a Triangle

In a previous article, we looked at how simple algebraic problems can be solved, the case in point being a rectangle. In this example, notice how similar steps have been followed, except that instead of a perimeter of a rectangle, we shall be considering the angles in a triangle. As before, the material has been [...]

The Smart and Easy Way To Solve a Triangle With 45-45-90 Degree Angles

Angles that have sides with a 45°/ 45°/90° usually have a unique ratio. The two legs are the exact same length, and the hypotenuse is that length times √2. Whenever you are given a triangle as shown above - one where two of its angles are 45° and the third is 90°, you can easily [...]

JSS 3 Mathematics Second Term Week 7 Topic: SINE AND COSINE OF ANGLES The sine (abbreviated "sin") and cosine ("cos") are the two most prominent trigonometric functions. All other trig functions can be expressed in terms of them. In fact, the sine and cosine functions are closely related and can be expressed in terms of each other. Definition [...]
