Given:
Hayden
minutes to complete each level of his video game.
He plays for
minutes.
To find:
The number of levels he will complete.
Solution:
We have,
Required time for each level = 
Total time = 
The number of level is




On further simplification, we get



Number of levels must be a whole number. So, approx to value to the preceding whole number.

Therefore, Hayden will complete 6 levels if he plays for
minutes.

Let the shorter leg = a.
The longer leg, b = a + 4.
The hypotenuse, c = a + 8
a^2 + b^2 = c^2
a^2 + (a + 4)^2 = (a + 8)^2
a^2 + a^2 + 8a + 16 = a^2 + 16a + 64
a^2 - 8a - 48 = 0
(a - 12)(a + 4) = 0
a - 12 = 0 or a + 4 = 0
a = 12 or a = -4
a = -4 is discarded because it is negative.
a = 12
b = 16
c = 20
The lengths are 12 m, 16 m, and 20 m.
84 degrees.
The two angles are alternate interior.
