This is a 30° 60° 90° triangle, so the rules below apply:
x is the short leg of the triangle, located across from the 30° angle. (In this problem, the short leg is labled b)
The hypotenuse leg is across from the right angle, and is always 2x (In this problem, the hypotenuse leg is labled c)
The long leg of the triangle is located across the 60° angle and is always x√3. (in this problem, the long leg is labeled a)
Answer: Michael has 87 comic books while David has 41 comic books.
Step-by-step explanation:
Let x represent the number comic books that Michael has.
Let y represent the number of comic books that David has.
Michael has 5 more comic books than double David's collection. The expression would be
x = 2y + 5
If together they have a total of 128 comics, it means that
x + y = 128- - - - - - - - - -1
Substituting x = 2y + 5 into equation 1, it becomes
2y + 5 + y = 128
3y + 5 = 128
3y = 128 - 5
3y = 123
y = 123/3
y = 41
Substituting y = 41 into x = 2y + 5, it becomes
x = 2 × 41 + 5
x = 87
