Answer:

m∠3 = 143°

Step-by-step explanation:

m∠1 = 53°

m∠2 = 180 - (90 + 53) = 37°

m∠3 = 180 - 37 = 143°

Answer:

143

Step-by-step explanation:

solution:

angle 1 = 53°

angle D = 90°

angle 3 = angle 1+ angle D [sum of two]

= 53°+90° [interior angle is equal ]

=143° [to an exterior angle]

a packe of cards conatins 4 red and 5 black cards. a hand of 5 cards is drawn without replacment. What is the proablity of all f

Vladimir79 [104]

Answer: Our required probability is 0.3387.

Step-by-step explanation:

Since we have given that

Number of red cards = 4

Number of black cards = 5

Number of cards drawn = 5

We need to find the probability of getting exactly three black cards.

Probability of getting a black card = $\dfrac{5}{9}$

Probability of getting a red card = $\dfrac{4}{9}$

So, using "Binomial distribution", let X be the number of black cards:

$P(X=3)=^5C_3(\dfrac{5}{9})^3(\dfrac{4}{9})^2\\\\P(X=3)=0.3387$

Hence, our required probability is 0.3387.

Free_Kalibri [48]

First: Find out how many of Jolie's balls are blue.

300 * 35% = 300 * 0.35 = 105 blue balls.

Second: Find the difference between the total number of balls and the blue balls to find out how many green balls Jolie has.

300 - 105 = 195 green balls.

Roger the park ranger was standing in a look out tower that was 200 ft tall. Looks down, sees a fire. Angle of depression is 7 d

Ainat [17]

Answer:

approx. 24.6 ft

Step-by-step explanation:

x=the distance of the fire from the base of the tower

200ft=the height of the tower

7 degrees=the angle of depression

Using these values you can draw a diagram that highlights that you need to use trig. to work out the answer.

Using Tan:

Tan 7=x/200 ft

multiply both sides by 200 ft

200*tan 7=24.55691218

approx. 24.6 ft
