6. PQR is a right angle triangle. QS is perpendicular to PR, and PQ has length 1. 1) Find QS and PS in-terms of 0.

2) By considering triangle QSR, find an expression for SR.

3) By considering triangle PQR, find PR in-terms of e.

4) Hence, show that
cos A = sec 0 -sin o tan 0.

Me solve this equation 2/3 + 4 equals -2

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
