Fоr the diаgrаm belоw, suppоse thаt T1 = 790 lbs. and T2 is unknown. Suppose we know that the resultant force is vertical. Given the force triangle associated with the problem: Identify all the angle measures of a, b, c: {Just type in the numerical value. Do not add in the degrees symbol.} a = [ans1] b = [ans2] c = [ans3] Once you have the force triangle set up, select the correct approach to help you solve for T2: Type in the correct letter from the choices below: [ans4] a. Law of Sines b. Law of Cosines c. either method described in a or b will work d. neither method described in a or b will work Type in the value for the magnitude of the tension in T2: [ans5] lbs Round your answer to the nearest WHOLE # {if necessary}
