1.explain what a radian measure represents using the unit circle as a reference. -A radian measure on a unit circle is the measure of the length of the arc at certain points on the unit circle. 2.how do special right triangles directly relate to a unit circle. -On the unit circle the radius of the circle is also the hypotenuse. therefore if you set the hypotenuse to be a value such as 1. the side (x,y) of the triangle will be the sine and cosine values on the unit circle.
B. Measure sides a, b, and c of the triangle with a tape measure and record these values in centimeters (cm) on your data sheet. C. Measure angles A and B of the triangle with a protractor and record on your data sheet. D. Using the values for the sides of the triangle that you measured in Step B, compute angles A and B by using the different trigonometric functions. E. Calculate the average value of the computed angle A by adding the three computed values of A and dividing by 3.

Answer: __9.0 – 2.0 = 7___________ What is the median? ___5.0 + 5.7 / 2 = 5.35 (there are two central values)__________ What is the mean? ___sum of all terms / number of terms = 5.7__________ What is the mode? __Their are no frequent occurring numbers, so there is no
A circumscribed circle touches each vertex of the triangle. There are also things called the incenter and the circumcenter. The incenter is the center of the inscribed circle and the circumcenter is the center of a circumscribed circle. The relation between a circle and a triangle is that
