Tanθ=(length of opposite side)/(length of side adjacent to the angle)

tanθ=12/9 *15 is the hypotenuse of the triangle. Don't use this for tan!

θ=53.13°
I am assuming you don't need this in radians?

erik [133]

Answer:

number of hours Alexander family ‘s sprinkler work = 20

number of hours Morgan family ‘s sprinkler work = 30

Step-by-step explanation:

Given in the question,

water output rate for the Alexander family ‘s sprinkler = 40 L

water output rate for the Morgan family ‘s sprinkler = 20 L

Suppose, number of hours Alexander family ‘s sprinkler work = x

Suppose, number of hours Morgan family ‘s sprinkler work = y

Equation1

x + y = 50

Equation 2

40x + 20y = 1400

x = 50 - y

Put this value of x in equation 2

40(50-y) + 20y = 1400

2000 - 40y + 20y = 1400

-20y = 1400 - 2000

-20y = -600

y = 30

Put this value of y in equation 1 to get the value of x

x + 30 = 50

x = 50 - 30

x = 20
