adj Activity 1-1: Identifying trig functions. 1. Consider the following right triangle. For each trig function shown, put the correct term in the numerator and denominator. sin θ =-, cos θ =-, tan θ =- CA sin φ =--, cos φ = tan φ =- , Pythagorean's theorem relates the three sides of the triangle. Based on the triangle above, Pythagorean' theorem is written as
Pre Calc/Trig NAME Evaluation Opportunity &**** 10:1710.2 Use the given information to solve for the remaining parts of the triangle. If two solutions exist, find both. Put your answers in the box provided. Round the sides to the nearest tenth and angles to the nearest degree. Law of Sines: sin Asin B sin C Law of Cosines a' =b+c-2bc cos A a 1. mZA= 36, mZB= 98, c = 18 2. a = 4, b=7, c= 9 Solution: Solution:
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...
8. Solve for the missing length and the other two angles in the triangle below. 15.0 64 A7.4 C Part I: Use the law of cosines to find the missing third side. (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)
use an inverse trig function to write theta as a function of x (There is a right triangle drawn. The hypotenuse is 2. Theta is the angle between the base and the hypotenuse. The base/adjacent side of theta is labeled(x + 1) The side opposite theta does not have a value.) Use an inverse trig function to write theta as a function of x:a) theta = sqrt [4 - (x + 1)^2] all divided by 2 b)theta = arccos [(x...
