Complementary angles are either of 2 angles that when added together equal 90. We can solve this by setting up a simple equation.
65+x=90
-65 -65
x=25
Using the equation above, we can see that ∠A=25.<u />
The way to determine the number of solutions is to complete the problem in multiple different ways.
this is written as
change the greater than or equal to sign to equal to in order to solve it
thus
dividing through by 2

Answer:
The fish depend on tiny organisms and/or plankton.
Step-by-step explanation:
The range of the set of scores is 13.
Here,
The set of scores:
7, 8, 11, 15, 17, 20
We have to find the range of the set of scores.
What is Range of set?
The range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set.
Now,
The highest number = 20
The lowest number = 7
Hence, Range of the data set = 20 - 7 = 13
So, The range of the set of scores is 13.
