thank you in advance!!

Question writer: it's customary to keep the degree sign off of the variable names in trig.

sin y = s/8

tan y = s/t

tan y = sin y  /   cos y

cos y = sin y / tan y

cos y = (s/8) / (s/t) = (s/8) × (t/s) = t/8

cos y = t/8,  third choice

step-by-step explanation:

worked it out i believe

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
