Academics

Problem: An observer, whose eyes are 1.81 m above the ground, is standing 31.8 m away from a tree. The ground is level, and the tree is growing perpendicular to it. The observer's line of sight with the treetop makes an angle of 19.9Â° above the horizontal.

Part A: How tall is the tree?

Would you be able to include the how you do it steps and equation and how to follow it thank you!!
