<h3>Answer: x = 34</h3>

=======================================================

Explanation:

A+B = 90 ... complementary angles add to 90 degrees

(x+22) + (x) = 90

x+22+x = 90

2x+22 = 90

2x = 90-22 ... subtract 22 from both sides

2x = 68

x = 68/2 ... divide both sides by 2

x = 34

--------------------

Extra info:

if x = 34, then angle A is x+22 = 34+22 = 56 degrees

Then we can see that A+B = 56+34 = 90, which confirms our answer

Answer:

3 hours

Step-by-step explanation:

If both the cars are moving in the same direction,

Speed of orange sports car = 60 miles per hour

Since, this car has already moved for 1 hour,

Distance covered by the sports car = speed × time

= 60 × 1

= 60 miles

Speed of the green van = 30 miles per hour

Since, green van has already moved for the duration = 3 hours

Distance covered by the green van = speed × time

= 40 × 3

= 120 miles

Therefore, distance between sports car and green van = 120 - 60

= 60 miles

Relative speed of orange sports car with respect to green van = Speed of sports car - speed of green van

= 60 - 40

= 20 miles per hour

Time taken by the orange sports car to cover 60 miles (Distance between sports car and green van) = $\frac{\text{Distance between the car and van}}{\text{Relative speed of the sports car}}$

= $\frac{60}{20}$

= 3 hours

Therefore, orange sports car will take 3 hours to pass the green mini green van.

ddd [48]

There are

$\dbinom{2n}2 = \dfrac{(2n)!}{2! (2n-2)!}$

ways of pairing up any 2 members from the pool of $2n$ contestants. Note that

$(2n)! = 1\times2\times3\times4\times\cdots\times(2n-2)\times(2n-1)\times(2n) = (2n-2)! \times(2n-1) \times(2n)$

so that

$\dbinom{2n}2 = \dfrac{(2n)\times(2n-1)\times(2n-2)!}{2! (2n-2)!} = \boxed{n(2n-1)}$
