That’s 12 since we calculate the sides
Answer: The required equation is

Thus, there are 71 students on the bus at the beginning of the route.
Step-by-step explanation:
Given: The number of students dropped off = 
The number of students remain on the bus = 
Let 'x' be the total number of students in the bus then we get the equation as

On adding 23 to 48, we get 71
Hence,
Therefore, There are 71 students on the bus at the beginning of the route.
Answer:
-11 for the first one and 0 for the second one
Step-by-step explanation:
Answer:
Use Pythagorean Theorem.
Step-by-step explanation:
To find any side of a right angled triangle, we use Pythagorean Theorem. It states that the square of hypotenuse is equal to the sum of squares of it's sides.
Let hypotenuse is a
Perpendicular is b
and base is c
According to the theorem:
a²= b² + c²
Add values and solve for the unknown variable / side.
If you had added the problem, I would have elaborated more but still this will help you out.
