What is angle B? Round the value to the nearest degree
zhuklara [117]

Answer: m\angle B=46\°

Step-by-step explanation:

For this exercise you need to use the Inverse Trigonometric function arccosine, which is defined as the inverse function of the cosine.

Then, to find an angle α, this is:

\alpha =arccos(\frac{adjacent}{hypotenuse})

In this case, you can identify that:

\alpha =m\angle B\\\\adjacent=AB=20\ cm\\\\hypotenuse=BC=29\ cm

Then, substituting values into \alpha =arccos(\frac{adjacent}{hypotenuse}) and evaluating, you get that the measure of the angle "B" to the nearest degree, is:

m\angle B=arccos(\frac{20\ cm}{29\ cm})\\\\m\angle B=46\°

Natali [406]

Answer:

A)1/4, 1/2 ,1/4

B)1

C)3/4

D)1

Step-by-step explanation:

THESE IS THE COMPLETE QUESTION:

A bucket contains one green block, one red block, and two yellow blocks. You choose one block from the bucket.

A)Find the theoretical probability that you will choose each color.

B)Find the sum of probability in(a)

C)What is the probability that you will not choose a red block?

D)Find the sum of the probabilities of choosing a red block and probability of not choosing a red block

EXPLANATIONS:

Sample of blocks: green,red, yellow, yellow

Total sample =4

Green sample = 1

Red sample 1

Yellow sample = 2

A)To find the theoretical probability that you will choose green.

i) P( choosing a green block)= green sample/Total sample

=1/4

To find the theoretical probability that you will choose red

ii)P(choosing a red block) = Red sample block/Total sample of blocks

= 1/2

To find the theoretical probability that you will choose yellow

iii) P(choosing a yellow block) = 1/4

B)The sum of probability in( a)

=P( choosing a green block) + P( choosing a Red block) +P( choosing a yellow block)

= 1/4 + 1/2 + 1/4

=1

C)P( Not choosing a red block) = 1 - 1/4

= 3/4

D)P(Sum of choosing a red block and not choosing a a red block)

=1/4 + 3/4

= 1
