In triangle OPQ, the measure of angle Q= 90 degrees, PO= 97 degrees, OQ= 65 and QP = 72 degrees. What ratio represents the cosine of angle O

It is 7 because it is the absolute value

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
