It won 12 times. 18 divided by 3 is 6, add six to six and you get 12 :)
101 + 4 x 22 = 101 + 88 = 189
The answer is 189
The way that I memorised how to do sin, cos, and tan is by the following: SOH, CAH, TOA
SOH = Sin is OPPOSITE / HYPOTENUSE
CAH = Cos is ADJACENT / HYPOTENUSE
TOA = Tan is OPPOSITE / ADJACENT
For example if we were to solve question 5
Sin T = 6 root 2 / 19
Cos T = 17 / 19
Tan T = 6 root 2 / 17
Repeat the steps for question 6
For the rest of the questions (7,8,9) you have to take the information given and figure out if you should us Sin, cos, or Tan. then plug the numbers in the calculator and while doing sin ^ -1, cos ^ -1, tan ^ -1
for example on question 7, to find the angle x they have given you the hypotenuse and the adjacent side so
cos x = 9 / 18
to find x plug: cos^-1 (9/18) in the calculator
I recommend learning the mnemonic SOHCAHTOA (it's very fun to say!)
Here is what SOHCAHTOA represents.
Sin - Opposite / Hypotenuse (SOH)
Cos - Adjacent / Hypotenuse (CAH)
Tan - Opposite / Adjacent (TOA)
The sine of an angle is the length of the side opposite of the angle divided by the length of the hypotenuse.
Thus, the length of the side opposite of the angle divided by the sine will give us the length of the hypotenuse.
The angle is 46 degrees. The length of the side opposite of the angle is 14. The hypotenuse is c.


The tangent of an angle is the length of the side opposite of the angle divided by the length of the side adjacent to the angle.
Thus, the length of the side opposite to the angle divided by the tangent of the angle will give us the length of the other leg.
The length of the side opposite to the angle is 14. The angle is 46. The unknown length of the side adjacent to the angle is b.
