Trigonometry For Dummies, 2nd Edition. By Mary Jane Sterling . The Pythagorean theorem states that a 2 + b 2 = c 2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two. The figure shows two right triangles that are each missing one side’s measure. In the left triangle, the measure of the

Section 4 Sine And Cosine Rule cimt.org.uk

To find an unknown side, say a, proceed as follows: 1. Make the unknown side the numerator of a fraction, and make the known side the denominator. Unknown Known = a 10: 2. Name that function of the angle. Unknown Known = a 10 = sin 36° 3. Use the trigonometric Table to evaluate that function. Unknown Known = a 10 = sin 36° = .588: 4. Solve for the unknown side. a = 10 ? .588 cm = 5.88 …

Multiplying both sides times 40, you're going to get, let's see. 40 divided by 30 is 4/3. 4/3 sine of 40 degrees is equal to sine of theta, is equal to sine of theta. Now to solve for theta, we just need to take the inverse sine of both sides. So inverse sine of 4 over 3 sine of 40 degrees. Put some parentheses here, is equal to theta. That will give us that angle here and we can use …
