The symbol for parallel lines is || . If there are parallel lines in with a triangle, then we can use angle pair relationships!
o In the figure above, what is the measure of angle b? (Use what you know about triangles)
o Can you now find the measure of angle a? (use what you know about alternate interior angles)
o Can you now find the measure of angle c? (use what you know about supplementary angles)

5, 6, 10 question: a. determine whether the side lengths form a triangle. (explain your reasoning) b. if it is a triangle, determine whether it is a right, acute, or obtuse triangle. (show your work)

Cos^2x+cos^2(120°+x)+cos^2(120°-x)i need this asap. pls me

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
