Trigonometry is a field of mathematics that studies the relationships that exist between the sides of a triangle and its angles. How much do you know about the properties of triangles? Have you worked with them much in the past?

These relationships and properties can be used to model many physical properties in the real world. One of these properties is called periodic motion, such as the motion made by a yo-yo going up and down. What kinds of periodic motion are you familiar with? Why might scientists and businesses be interested in tracking this type of motion using equations?

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
