Answer:
x = 4
Step-by-step explanation:
This is special right triangles
For the triangle on the bottom, the shorter leg is x, the longer leg is x * √3, and the hypotenuse is x *2. This means that the shorter leg is 2 since you the longer leg is that side multiplied by √3. The hypotenuse is x *2, which is 2 * 2 which equals 4.
Now we have one side of the bigger triangle. This triangle is a 45-45-90 triangle, and the rule is that the two legs are x, and the hypotenuse is x *2. Since we found a leg and not the hypotenuse of the bigger triangle, and the two legs are congruent, that means x is 4.
It will take 2 hours for the ambulance to pass the police car.
Given that a police car leaves a crime scene heading east directly towards the hospital at 72 kilometers per hour, and an ambulance leaves a quarter of an hour later and also heads directly east towards the hospital at 81 kilometers per hour, to determine how long will it take for the ambulance to pass the police car, the following calculation must be performed:
- 72 x 0.25 = 18
- 81 - 72 = 9
- 18/9 = 2
- 72 x 0.25 + 72 x 2 = 162
- 81 x 2 = 162
Therefore, it will take 2 hours for the ambulance to pass the police car.

Answer:
4
Step-by-step explanation:
If q=5, 3 times 5 would be 15. p is 3, so then 15 - 3 = 12. When 48 is divided by 12, the answer would be 4.
