    Right Triangles Word Problems with Illustrations and Solutions 1. Solve the right triangle ABC given that c = 18 cm and b = 9 cm. To find the remaining side a, use the Pythagorean Theorem: a2 + b2 = c2 a2 = c2 - b2 a2 = (18cm)2-(9cm)2 a2 = 324cm2 – 81cm2 a2 = 243cm2 a = 15.59cm 2. Ben and Emma are out flying a kite.

    The graphs of the sine and cosine functions Let's continue to use t as a variable angle. A good way for human beings to understand a function is to look at its graph. Let's start with the graph of sin t. Take the horizontal axis to be the t-axis (rather than the x-axis as usual), take the vertical axis to be the y-axis, and graph the equation y = sin t. It looks like this. First, note that it is periodic of period 2. Geometrically, that means that if you take the curve and slide it 2 either

    1. N/a 2.  using Law of Sines and Law of Cosines. You get two different triangles. The one combination you can't have is where A is opposite the b. Maybe your notation already specifies this, but I don't think so, otherwise there is no problem. If you try to construct a triangle with the 70 degree angle opposite the side of length 5, the Law of Sines would give sin x = (7/5)sin 70 = 1.316, which is impossible. With angle A = 70 opposite the side of length 7, the Law of Sines gives  sin x = (5/7)sin
