Question

A tree casts a shadow 15 m long on the level of ground, when the angle of elevation of the sun is 45°.Find the height of the tree​

Answer 1

Answer:

these two problems are related to the same estado cos 15 longer so you can use the elevation formula is equal to 45 degrees the height of the tower B 15 into cos 45 that is equal to 15 by 1 by root to the answer is 15 by root

Answer 2

Answer: 15 m
Explanation: Base = 15m (given)
to find perpendicular or opposite
we know that P/B= tan
tan 45= P/ 15
1 = p/15
therefore, P = 15*1= 15 m
