Hi!
Rules for solving 30-60-90 triangles are as follows:
* The hypotenuse is double the short leg.
* The short leg times √3 is the long leg
To solve then, we divide 4√21 by √3 and get 4√7. That is x, and to get y we multiply by 2. That is 8√7.
Hope this helps! :D
Answer
No missing money
Step-by-step explanation:
Original money given to the waiter = $30
Each person paid $10
The waitress comes back with the waitress comes back and said the bill is $25
They gave her $2 for the tip
if each got $1.00 back
Balance = $1.00 × 3
= $3.00
That means each paid $9×3 = $27 including $2 .00 tip(recall that cost of the meal is now $25 plus $2 tip)
Each of them got $1.00 back
Total money spent = (cost of meal + tip) + balance of $3.00 given to them
= $27 + $3
= $30
Therefore, there is no missing $1.00
