-5n=13-3m solve for m

Step-by-step explanation:

-5n = 13 - 3m

Subtract 13 from both sides

-5n - 13 = -3m

Multiply the whole equation by (-1)

-5n *(-1) - 13*(-1) = -3m*(-1)

5n + 13 = 3m

Divide both sides by 3

step-by-step explanation: divide the number of feet with the nu,ber of milrs and there your answer

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
