nooo you can't cancel it, 3-x isn't the same as x-3 that's like saying 3-5 is the same as 5-3

Posted from TSR Mobile

What I did was factorised it to (3-x)/(3-x)(-3x-4) then cancelled out to get 1/-3x-4

I got 30.1 to 1dp because the whole angle was 60.1 but x was not incliding the 30 so it was 60.1 minus 30

The exact Answer for the trial and improvement was 3.7504 which is obviously closer to 3.8 then 3.7 so the answer is 3.8
X= 3.8

Wasn't the last question like 1/2 * 7 * 8 Sin(X) = 18

56Sin(x) = 36

Sin^-1(36/56) = X

x = 40

???

I think I did it wrong then.

What you've done is correct but this is only part of the method as this gives a different angle to the one it asked, so there was more working :smile:

If you do it correctly it works

eg. 6 - 4 is the same as -4 + 6

Sorry but it's wrong, the answer was 3.7

3.8 is correct

3.7 = Small
3.75 = Small
3.8 = Big

Always the odd one out, regardless how close it is technically.
