Find x and y
From the triangle, we can see that x is the longest side (i.e. the hypotenuse)
The sin of an angle is:
The relationship between the given angle (30 degrees), x and 5/2 is:
Cross Multiply:
Solve for x
So, the expression becomes
To solve for y, we make use of Pythagoras theorem:
Substitute 5 for x
Solve for
Square root of both sides
Express 75 as 25 * 3
Split:
$1650 / 5 people = $330 spent on food for a month for each person in the family
330 * 8 = 2640
