Answer:
the correct answer is 4 and 21
Answer:
9) C: x=4, y=2rt3
10) A: XY/YZ
11) A: XY/XZ
Step-by-step explanation:
9 - that is a 30, 60, 90 triangle so the ratios will be a, root3a, 2a
10 - tan = opposite / adjacent
11 - cos = adjacent/hypotenuse

Answer:
B
Step-by-step explanation:
If two lines are parallel, then their slopes are equal.
Line 1: y = 2x + 6
slope = 2
Line 2:
(1 , 5) ; (3,9)

Slope of line 1 = slope of line 2 = 2
So, line 1 and line 2 are parallel
