<h2>Sine rule:</h2>
Law of sine:
![\sf \boxed{\bf \dfrac{a}{Sin \ A}=\dfrac{b}{Sin \ B}= \dfrac{c}{Sin \ C}}](https://tex.z-dn.net/?f=%5Csf%20%5Cboxed%7B%5Cbf%20%5Cdfrac%7Ba%7D%7BSin%20%5C%20A%7D%3D%5Cdfrac%7Bb%7D%7BSin%20%5C%20B%7D%3D%20%5Cdfrac%7Bc%7D%7BSin%20%5C%20C%7D%7D)
a = y
A = 31°
b = 17 mm
B = 117°
![\sf \dfrac{y}{Sin \ 31^\circ}=\dfrac{17}{Sin \ 117^\circ}\\\\](https://tex.z-dn.net/?f=%5Csf%20%5Cdfrac%7By%7D%7BSin%20%5C%2031%5E%5Ccirc%7D%3D%5Cdfrac%7B17%7D%7BSin%20%5C%20117%5E%5Ccirc%7D%5C%5C%5C%5C)
![\sf y = \dfrac{17}{Sin \ 117^\circ}*Sin \ 31^\circ\\\\ y = \dfrac{17}{0.89}*0.515\\\\y = 9.84 \ mm](https://tex.z-dn.net/?f=%5Csf%20y%20%3D%20%5Cdfrac%7B17%7D%7BSin%20%5C%20117%5E%5Ccirc%7D%2ASin%20%5C%2031%5E%5Ccirc%5C%5C%5C%5C%20%20y%20%3D%20%5Cdfrac%7B17%7D%7B0.89%7D%2A0.515%5C%5C%5C%5Cy%20%3D%209.84%20%5C%20mm)
Helloo, i don’t see the image seen above, is that the only picture?
You add +7 to both sides and then divide by 9 to get the x alone.

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
