When playing a board game, you spin two spinners with congruent sectors numbered 1 through 7 as shown. If the sum of the numbers you spin is 12, 13, or 14, you win. What is the probability that you win? (Enter your answer as a
fraction.)

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

thats not a system of equations, that is a solution

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

the answer is c 150
