Help please!!!! I will really appreciate it please help
Scorpion4ik [409]

Answer:

Correct answer is x = 28°

Step-by-step explanation:

Okay we know Angle A is 2x + 2

Angle B is 90

Angle C is 180 - 148 = 32 ( straight line angle is 180)

Sum of all angles should be 180 in a triangle

which means

A + B + C = 180

2x + 2 + 32 +90 = 180

2x + 124 = 180

2x = 180-124

2x = 56

x = 56/2

x = 28

You place a bet on the number 21 in roulette. the probability of winning is 1 38 , and the company hosting the casino night for
inysia [295]
1 in 38.  
Nothing much to say about this problem. There are 38 spaces on the roulette wheel and an every space on a fair wheel has an equal probability of being selected. So you would expect 1/38 = 0.026315789 = 2.6315789% of the time for the number 21 to show up.

I need help for #1 (an explanation would be great too).
Ivan

Answer:

±6i√2

Step-by-step explanation:

Recall that the square root of a negative number is imaginary, which is shown by the use of "i."

Examples:  √4 = ±2; √4 = i√4 = ±i2

Then √72 = ±√36√2 = ±6√2, and

   

      √(-72) = ± i√36√2 = ±6i√2

         

Note that this is identical to the result shown in the problem:  √(36·2·(-1) )
