You are standing on an elevated observation platform 135135 feet away from a tree on which you spot a monkey. You measure the angle of depression to the bottom of this tree to be 8∘8∘, while the angle of elevation to the top of the tree is 29∘29∘. The angle of elevation to the monkey is 24∘24∘. The height of the observation platform is? The height of the tree is? The height of the monkey above the ground is?  in feet

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products. 

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
