Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Mathematically, for us to have a right triangle, Pythagoras’ theorem must be obeyed
From the theorem, the square of the hypotenuse (longest side) equals the sum of the squares of the two other sides
Let us take a look at the given set of numbers:
2 square is not same as 1 squared + 1 squared
9 squared is not equal to 3 squares + 5 squared
7 squared is not equal to 4 squared + 3 squared
But;
root 2 squared equals 1 squared plus 1 squared and that is our answer
This is a right triangle, and the legs are 8 and 15
8/15 represents the division of the legs, then it must be tangent
tangent is the relation of opposite leg and adjcent leg to the angle
The opposite leg must be 8, and the adjacent leg must be 15
Then we must find the angle which opposite leg be 8 and adjacent leg be 15
This is the angle B
Then 8/15 is the tangent to angle B
Answer: First option tan B
The range is the distance between the largest and smallest numbers in a set of data (Largest number - smallest number = range)
Here we know the smallest number (20) but the largest number is at some point between 60 and 80.
To find the increment of each line in-between 60 and 80:
80-60 = 20
20/5 = 4
So the values will be 60, 64, 68, 72, 76, 80
Therefore the largest value is at the 76 mark
Now to find range by subtracting the smallest number from the largest number:
76-20 = 56
The range is 56
