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...

i need help with these 3 homework problems, thank you ! Solve a Triangle Using the Law of Sincs (SSA) Ambiguous Case Suppose that the measure of angle A and the lengths of sides a and b of a triangle are given. Depending on the length of side a (shown in red) relative to the length of the altitude h, we have four different scenarios No triangle One right triangle One oblique triangle Two triangles: One acute and one obtuse...

(2 points) Part ll: Use either the law of cosines or the law of sines to find the measure of angle C. 2 points) Part IlI: Use any method you like to find the measure of angle B. (1 point)
Find the measures of the angles of the triangle whose vertices are A = ( - 2,0), B = (2,1), and C=(2,-3)
1.) Given that the perimeter of a triangle is 216. If the angles of the triangle are in the ratio 5:6:7, determine the longest side of the triangle. 2.) 4 times the sine of a certain angle is 6 times of the square of the cosine of the same angle. Find the angle in degrees if it’s in the first quadrant. 3.) Determine k so that the points A(3,8), B(-1,0), and C(k,-2) are the vertices of a right triangle with...
