Answer/Step-by-step explanation:

Recall the acronym SOHCAHTOA. This is what we would apply as appropriate in each case.

8. θ = 40°

Opp = m

Adj = 20

Thus, apply TOA

Tan (θ) = opp/adj

Plug in the values

Tan (40) = m/20 (equation)

20×Tan(40) = m

m = 16.7820

9. θ = 22°

Hyp = w

Adj = 18

Thus, apply CAH

Cos (θ) = adj/hyp

Plug in the values

Cos 22 = 18/w (equation)

w×cos 22 = 18

w = 18/(cos 22)

w = 19.4136

10. θ = 35°

Hyp = 55

Opp = x

Thus, apply SOH

Sin θ = opp/hyp

Plug in the values

Sin 35 = x/55 (equation)

55×sin 35 = x

x = 31.5467

11. θ = 33°

Hyp = 19

Adj = x

Thus, apply CAH

Cos θ = adj/hyp

Plug in the values

Cos 33 = x/19 (equation)

19×cos 33 = x

x = 15.9347

12. θ = 17°

Opp = 7

Hyp = x

Thus, apply SOH

Sin θ = opp/hyp

Plug in the values

Sin 17 = 7/x (equation)

x×sin 17 = 7

x = 7/(sin 17)

x = 23.9421

13. θ = 40°

Opp = 15

Adj = x

Thus, apply TOA

Tan θ = opp/adj

Plug in the values

Tan 40 = 15/x (equation)

x×Tan 40 = 15

x = 15/(Tan 40)

x = 17.8763

Solve the equation<br> 15x+2=45x+4
BaLLatris [955]
15x + 2 = 45x + 4

Subtract 2 from both sides, as well as subtracting 45x from both sides.

15x - 45x = 4 - 2

-30x = 2

Divide both sides by -30.

x = 2/-30

x = - 1/15

• back= 0.7 mm

• each page= 0,14 mm

ask:

calculate the minimum thickness...?

answer:

a. 200 p × 0,14 = 28 mm

b. front + back = 0.7+0.7= 1.4 mm

Thickness= 28+1,4 = 29,4 mm

I hope this helps

I NEED HELP ASAP!!<br><br> Subtract.<br><br> -30-27= ?<br><br> -5-(-4)= ?
pashok25 [27]
-30-27= -57
When both numbers are negative, they are “added” in a sense, but remain negative.

-5-(-4)= -1
You have to multiply the (-4) by the “invisible” -1 on the outside before you add/subtract.
