Given AABC is circumscribed by a circle of radius R the radius of the circle can be found using the formula shown, where side b is opposite angle B. Find the radius of the circle shown. > APPLICATIONS 47. Planetary distances: In a solar system that parallels our own, the planet Sorus can be seen from a Class M planet with the naked eye, but as the diagram indicates, the position of Sorus is uncertain. 50 Exercise 47 Sorus 51 Assume the orbits of Sorus/51 Sun both planets are roughly circular and that the viewing angle 0 Class M is about 20°. If the 82 Class M planet is 82 million miles from its sun and Sorus is 51 million miles from this sun, determine the closest and farthest possible distances that separate the planets in this alignment. 51. 48.

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.
