I . Given triangle ABC with A = 32° , B = 105°, and b = 25 inches, find the length of side a. Round to the nearest tenth. Hint: This is not a right triangle. You'll need to use the Law of Sines or Law of Cosines to solve for the missing side. If you're not sure which, draw the triangle and see whether you have ASAAAS (Law of Sines) or SAS/SSS (Law of Cosines).

Here is the question: Let r be the radius of the incircle of triangle ABC on the unit sphere S. If all the angles in triangle ABC are right angles, what is the exact value of cos r? Note in spherical geometry the angles sum is>180 Using below picture (this is what we are given), we should know angle b and the angle at the perpendicular. If we find the length on...

Use the Law of Sines to solve for all possible triangles that satisfy the given conditions. a = 39, c = 41, 2A = 38° Step 1 The Law of Sines says that in triangle ABC, you have Step 2 To find the missing values for the triangle, which are B, C, and b, since you have A, a, and c, you can use the Law of Sines. Set up and solve the relation for C, using a, c, and...

8.4 Which of the following is not true? Choose the correct answer. A. We verify an identity by trying to transform one side of the identity into the exact trigonometric expression that appears on the opposite side. B. If one side of an identity includes a trigonometric expression involving the sum or difference of sine and cosine or the product of sines and/or cosines, then to verify the identity always start by transforming the other side of the identity. C....
