The two angles form a right triangle which is 90 degrees.

Add the two to equal 90:

3x-8 + 4x = 90

simplify:

7x-8 = 90

Add 8 to both sides:

7x = 98

Divide both sides by 7:

x = 14

The pond can hold 400 water liters.

y = 3.915(1.106)x is an expression.

<h3>To find </h3>

The pond will be full by the end of the day.

<h3>How many days it will take?</h3>

Let x be the day and y be the hold of water.

When pond can hold 400 liters of water the x will be

400 = 3.915×1.106x

400 = 4.33 x

    x = 92.37 ≈ 93

Thus, the pond will be full by the end of the day in 93 days.
