Explanation: I drew a diagram and dived all the measurements in meters by 10 to get cm which showed that the ladder (in the diagrams scale) was 32cm long but as i had divided i needed to time it by ten to get the answer. after multiplying 32cm by 10 i got 3.2 meters.
This is because if you draw a diagram, and label all the sides of the triangle (opp, hyp, adj), the adjacent angle is 3m. You can now use the sine rule to find the hypotenuse (length of ladder) by doing: cos 30= 3/h. You divide cos 30 by 3 and you get the answer of 3.64m rounding to 2 decimal places.
