I believe so. (TRUE). a square has all equal sides so if the figure is just alike, its a reg quad.
        
             
        
        
        
Use trigonometry.
tan30° = perpendicular / base
Here for angle 30° , x is perpendicular while 10 is the base.
tan30° = 1/√3
1/√3 = x/10
 x = 10/✓3
By rationalising 
x = 10√3/3

Answer: 33.6 min
Step-by-step explanation:
Volume = L*W*H = 9 * 13 * 14 = 1638 in^3
Vol2 = 21 * 25 *35 = 18375 in^3
18375/1638 = 11.2 times bigger, so 3min * 11.2 = 33.6 minutes
 
        
                    
             
        
        
        
P(orange and then a purple) is 15/56.
P(two purples in a row) is 6/56.
<u>Step-by-step explanation:</u>
- A bag contains 3 purple and 5 orange jelly-beans.
- The total jelly-beans in the bag = 3 purple + 5 orange = 8 jelly-beans.
<u>Without replacement, find P(orange and then a purple) :</u>
P (orange) = No.of orange jelly-beans / total jelly-beans.
⇒ 5 / 8
P (purple) = No.of purple jelly-beans / remaining jelly-beans from the total
⇒ 3 / 7
P(orange and then a purple) = P (orange) × P (purple)
⇒ 5/8 × 3/7 
⇒ 15/56
<u>Without replacement, find P(two purples in a row) :</u>
P (1st purple) = No.of purple jelly-beans / total jelly-beans.
⇒ 3 / 8
P (2nd purple) = remaining no.of purple jelly-beans / remaining jelly-beans from the total.
⇒ 2 / 7
P(two purples in a row) = P (1st purple) × P (2nd purple)
⇒ 3/8 × 2/7
⇒ 6/56
