b) How long is the shadow when the sun is at an angle of elevation
of 45°?​

Answer 1

Answer:

Step-by-step explanation:

$a)\\ tan60=\frac{30}{s}\\ \\ s=\frac{30}{tan60}\\ \\ s=\frac{30}{\sqrt{3}}\\ \\ s=10\sqrt{3}m\\ \\ s\approx 17.32m\\ \\ b)\\ \\ tan45=\frac{30}{s}\\ \\ s=\frac{30}{tan45}\\ \\ s=30m$
