Answer:
137°
Step-by-step explanation:
If we know that a set of angles form one of these special relationships, we can determine the measure of the other angle. To determine the supplement, subtract the given angle from 180. 180 - 43 = 137° The supplement of 43° is 137°.

Answer:
√a(√a + 2) a - 2√a
----------------- = -----------------
a - 4 a - 4
Step-by-step explanation:
I am assuming that by "sqrt(a)/sqrt(a)-2" you meant:
√a
----------
√a - 2
To rationalize the denom., multiply numerator and denom. of this fraction by the conjugate of √a - 2, which is √a + 2:
√a(√a + 2)
-----------------
a - 4
Mean: Add all the numbers and divide by the amount of numbers.
20 + 0 + 7 + 10 + 11 + 0 + 25 + 15 + 1 = 89
89/9 = 9.889 (rounded)
Mean = 9.889 (rounded)
Median: Reorder from least to greatest, and the middle number is the median.
0, 0, 1, 7, 10, 11, 15, 20, 25
The middle number is 7
Median = 7
Mode: The number that shows up the most.
Mode = 0, which shows up one time more than all the other numbers
Range: Subtract the greatest number with least number
25 - 0 = 25
Range = 25
hope this helps
