When designing a truss, a truss builder might know the base angle measurement and the lengur UI te te verleeu. 11 compute the height of the king post. Let's take a look at some right triangles to see whether knowing the measure of an acute angle of a right

triangle and the length of one of the sides is enough to find the lengths of the other two sides.

You will use GeoGebra to explore the trigonometric ratios when an acute angle is fixed for a given right triangle. Go to trigonometric ratios

and complete each step below. The right triangle represents half of a king post truss. If you need help, follow these instructions for using

Amovie producer conducted a survey after the screening of his movie to find out how the film would be received by viewers from different age groups. the columns in the two-way table indicate the numbers of viewers who rated the film on a four-point scale: excellent, good, average, and poor. viewer's age group excellent good average poor marginal totals 16-25 52 42 12 7 113 26-35 33 50 5 9 97 36-45 58 12 28 34 132 which of these observations is supported by the data in the table? note: a rating of good or excellent means the audience liked the movie, while a rating of poor means the audience disliked the movie. a. the majority of the audience in the 26-35 age group disliked the movie. b. among those who liked the movie, the majority were in the oldest age group. c. among those who disliked the movie, the majority were in the 26-35 age group. d. the majority of the audience in the 16-25 age group liked the movie. e. the majority of the audience from all the age groups disliked the movie
