Okay first, use the sin rule (
![\frac{SinA}{a} = \frac{SinB}{b}](https://tex.z-dn.net/?f=%20%5Cfrac%7BSinA%7D%7Ba%7D%20%3D%20%20%5Cfrac%7BSinB%7D%7Bb%7D%20)
so
![\frac{Sin120}{35} * 30 = SinB](https://tex.z-dn.net/?f=%20%5Cfrac%7BSin120%7D%7B35%7D%20%2A%2030%20%3D%20SinB%20)
sin^-1 this and you get 47.928....this is angle ADB
and as it is on a straight line, 180 - this angle gets ADC
180 - 47.928.... = 132.07
They equal to 180 because they are supplementary angles
To find the number of full trucks we can do 1006 / 12. This gives us 83.8333. That is, 83 full trucks and a bit left over.
The bit left over is the answer to the second part, the last truck. 0.8333 is the same as 10/12, so the last truck will have 10 cars in it. If we didn’t know that fraction, we could find the answer by saying 12x83 = 996. 1006 - 996 = 10.
So the final answer is: 83 full trucks and 10 cars in the last truck.
