Answer:

  QO = 52.6 ft

Step-by-step explanation:

The trig relation that involves sides adjacent and opposite the angle is ...

  Tan = Opposite/Adjacent

  tan(5°) = (4.6 ft)/x

  x = (4.6 ft)/tan(5°) ≈ 52.578 ft

The length of QO is about 52.6 feet.

JulijaS [17]
-------------------------------------------------------------------------------------------------
Assumptions
-------------------------------------------------------------------------------------------------
Let x be the amount of 25% orange juice
Let y be the amount of 10% orange juice

-------------------------------------------------------------------------------------------------
There are 15 litres of 13% orange juice
-------------------------------------------------------------------------------------------------
x + y = 15

-------------------------------------------------------------------------------------------------
The 15 litres of juice is 13% orange juice
-------------------------------------------------------------------------------------------------
0.25x + 0.1y = 15 x 0.13
0.25x + 0.1y = 1.95

-------------------------------------------------------------------------------------------------
Rewrite the equations and solve for x and y
-------------------------------------------------------------------------------------------------
x + y = 15 ----------------------- (Equation 1)
0.25x + 0.1y = 1.95 ----------- (Equation 2)

(Equation 1):
x + y = 15
x = 15 - y  ----------- (Substitute into Equation 2)

0.25 (15 - y) + 0.1y = 1.95
3.75 - 0.25y + 0.1y = 1.95
0.15y  = 1.8 
y = 18 ÷ 0.15
y = 12 ------------- (substitute into Equation 1)

x + y = 15
x + 12  = 15
x = 15 - 12
x = 3

x = 3 and y = 12
