Necesito ayuda con esto plz, es para hoy xd (Signos Algebraicos de las Funciones Trigonométricas en los cuadrantes)

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

the answer is 31.27mph

step-by-step explanation:

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
