Next week, we will be covering several topics: 1) special right triangles, 2) ratio trigonometry, and 3) angle of elevation and depression. If you can understand the first two concepts, the third concept is easy to do.
Here two videos about the two types of special right triangles:
For extra credit, rewatch the videos and answer the following questions and turn them in on a sheet of paper Monday!
1) From the first video, if x = 11, what is the value of the hypotenuse in a 45-90-45 triangle?
2) From the second video, if x = 1.5, what are the values of all three sides in a 30-60-90 triangle?
3) From the third video, if a = 21, b = 28, and c = 35 what are the trigonometric ratios from a non right angle?
