a) using law of cosines
to find the 3rd side
BC = sqrt [ 15.8^2 + 7.4^2 - 2* 15.8 * 7.4 cos 54 ]
BC = 12.92
missing side = 12.92
b) using law of sines to find measure of C
12.92 / sin 54 = 15.8 / sin C
C = 81.63
c) sum of all sides of triangle is 180
B = 180 - ( 81.63 + 54 )
B = 44.37
8. Solve for the missing length and the other two angles in the triangle below. 15.0...
Given triangle ABC shown, find the length of side a. Round to the nearest ronth. 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. 13 53 15 C
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).
Do not use I=delta/S!!! Use 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...
