you will need 30 square feet
By using the distance formula
Let Ale’s money=a
Let Leo’s money=L
a=2L+3
You may have to rearrange any multiple choice answers algebraically, but they should all simplify down to the a= equation.
In problems like this, you can solve by thinking of how the word problem defines the variable. Ale is defined as twice Leo, plus three.
Answer:
Sinx = 5/13
cosy = 5/13
cosy = sinx ; they both share a proportional relationship
Step-by-step explanation:
From the attached triangle, since the triangle is right angled, we can use trigonometric functions where ;
sinx° = opposite / hypotenuse
From Pythagoras ;
Hypotenuse = √(opposite² + adjacent²)
Hypotenus = √(12² + 5²)
Hypotenus = 13
Sin x° = opposite / hypotenus = 5 / 13
Sin x° = 5/13
Cos y = adjacent / hypotenus = 5 / 13
Hence,
sinx = cosy
Therefore, they both share a proportional relationship.
