Hence, mathematically, altitude of a triangle can also be defined as twice the area …The law of cosines allows us to find angle (or side length) measurements for triangles other than right triangles. The third side in the example given would ONLY = 15 if the angle between the two sides was 90 degrees. In the example in the video, the angle between the two sides is NOT 90 degrees; it's 87. As such, that …180° - 115° = 65°. The measure of angle x is 65°. Example #2: Determine the measure of angle y. Notice that this triangle has a right angle in the bottom left corner. This angle measures 90°. Step 1: Add the measure of the given angles together. 52° + 90° = 142°. Step 2: Subtract the sum from 180°.Its area is 15.59 ft². Since we know that all three sides are 6 feet long, we can use Heron's formula to work out its area in square feet. Calculate the perimeter: p = 3 × (6 ft) = 18 ft. Divide the perimeter in half to get the semiperimeter: s = ½p = 9 ft. Use Heron's formula: A = √ [ s (s−a) (s−b) (s−c) ]

Sep 18, 2016 · To find theta, you use the arccos function, which has the same relationship to cosine as arcsin has to sine. And again, you may see arccos written as cos^ (-1)theta. So if costheta=a/c, then arccos (costheta)=arccos (a/c) or theta=arccos (a/c). To answer your question directly, any trig function can be used to find theta, as long as you have at ...
