Am i correct? Chicago Ave. is parallel to Ontario Street. What is the relationship between angles 5 and 9. (Diagram below) a. They are same-side interior angles. b. They are corresponding angles. c. They are alternate interior angles. d. They are alternate exterior angles. **I believe the answer is A If the slope of line l is - 2 / 5, what is the slope of line m so that line l is perpendicular with line m? a. - 2/5 b. -5 / 2 c. 2 / 5 d. 5 / 2 ** I believe the answer is B or C
2nd question: when the slope is the negative reciprocal then the line is perpendicular example. slope = 1/2 .. then perpendicular slope is -2/1
Which of the following are not lengths of the sides of a triangle? a. 2, 3, 4 b. 2, 3, 2 c. 2, 3, 3 d. 2, 3, 6 I believe it is D
So number 2 is A? @ajspeller
Nope .. when you negate and flip you end up with -(-5/2) which results in positive 5/2
Diagram for 1
Can you help me out one last time? @jim_thompson5910
in #1, I don't see angle 9
I meant 7 @jim_thompson5910
