Answer:
x = 2√2
Step-by-step explanation:
This is a 45-45-90 triangle. This means that if the legs are x, then the hypotenuse is x√2.
In the case, the hypotenuse is already 4. So we have the equation:
x√2 = 4
Multiply both sides by √2
2x = 4√2
Divide both sides by 2
x = 2√2
you would need to divide 90 by 3 because that is how many there are in each row.
you will get 30
then you need to multiply 30 by 2 becanse that is how many are in the rows on the left.
you will get 60,
so there are 60 seats on the left.
