Answer:
Neither
Step-by-step explanation:
The slope of PQ is -3.
The slope of RS is 3.
Parallel lines have the same slope. The slopes for perpendicular lines are the opposite of the reciprocal. PQ and RS are intersecting lines, but not parallel or perpendicular.
Note the answer must be positive because if sin>0, then csc > 0.
There are two ways to do this problem.
1) Use a trig identity:
Sub in value for cot
2) Use a right triangle and SOH CAH TOA
cot = 1/tan = adjacent/opposite = -21/20
Therefore adjacent side = 21, opposite side = 20
Use pythagorean thm to find hypotenuse:
csc = 1/sin = hypotenuse/opposite = 29/20
Hope this helps.
Answer:
yes. 7 times 4.3 is equal to 30 and the first equations symbol is less then or equal to. good luck and hope this helps!
