The ladder has a length of 3 m and is leaning against the wall, and its inclination to the wall is 45°. How high does it reach?

Correct answer:

h =  2.1213 m

Step-by-step explanation:

α=45  β=90α=9045=45  c=3 m  sinβ=h:c  h=c sinβ sin45°=1/2  h=c sinβ=c sin45° =3 sin45° =3 0.707107=2.121=2.1213 m
