A ladder is placed so that it makes an angle of 76° with the ground. When the foot of the ladder is 1.7m from the foot of the wall, how high up the wall does the ladder reach?

Hey. Unfortunately, I cannot give you the answer but I will give you the steps. First, create the triangle with the given information. After, think about the sides, what are there and what are missing i.e. Opposite, Adjacent or Hypotenuse. hen, think about which of the formulas SOH, CAH or TOA you would use and then substitute the numbers in.
Hope it helps! (:

Draw the situation (it’ll be a right angled triangle) that you can do some trigonometry on

Yep, it mentions in the question "When the foot of the ladder is 1.7m from the foot of the wall" so you're completely right.
