Question

A man standing on a on 3.4 m tall latter is leaning at 0=70° against a wall.

Answer 1

Answer:

h = 3.19m

Explanation:

This system has a shape of a rectangular triangle.

So :                                 sin(Θ) = the ladder height / h

      sin(Θ) x the ladder height = h

                            sin(70) x 3.4 = h

                                              h = 3.19m
