Sin j=
Cos j=
Tan j=

Step-by-step explanation:

sin J=42/58=21/29

cos J=40/58=20/29

tan J=42/40=21/20

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
