A ladder makes alpha angle with the ground. Its bottom is pulled by a And due to this it slips by b with the wall and makes beta angle with the wall then a is equal to
a. b tan(alpha+beta)/2
b. b tan(alpha+beta)
c. b tan( ( alpha+beta)/2)
d. (b tan((alpha+beta)/2))/2

A crow starts off in his nest near the ground. It leaves its nest, flying along the ground, due east for 60m. The crow then travels north for 80m, still flying along the ground. Then the crow flies straight up into the sky for 30 meters.
a. Draw a 3D diagram that represents the crowβs flight path.Β
b. At this point, how far is the crow from his nest?Β
c. What is angle of elevation that a baby crow would have to look up to see the adult crow from
the nest?Β
