This uses the Pythagorean Theorem, which is a^2 + b^2 = c^2 . All you need to do is switch that formula around and you can get the answer easily.
10^2 + b^2 = 16^2
100 + b^2 = 256
b^2 = 156
b= 12.489, or 12.49 rounded
Answer:
14 hrs
Step-by-step explanation:
Graphically we can see the line decreases one grid vertically (720 gal) for every one grid horizontally (1 hour)
If we imagine extending the line to the right, the next dot will occur at 12 hrs and 1440 gallons followed by the final dot on the x axis (zero gallons) at 14 hrs
We could also write an equation in slope intercept form
b = 10080 gallons
m = -720 gal/hr
y = -720x + 10080
we want to know the hours x when gallons y = 0
0 = -720x + 10080
720x = 10080
x = 10080/720 = 14 hrs
Answer:
Adjacent, x = 100
Step-by-step explanation:
80 and x are on a straight line. Straight lines = 180 degrees. 180 - 80 = x
Vertical angles are opposite of each other, not next to each other.
