Answer: 4.25, 15, and 38.7°

Step-by-step explanation:

Use SOHCAHTOA

Sine is opposite over hypotenuse

Cosine is adjacent over hypotenuse

Tangent is opposite over adjacent

1.) tan(28) = x/8

8*tan(28) = x

x = 4.25

2.) tan(28) = 8/x

8/tan(28) = x

x = 15

3.) tan(x) = 4/5

x = arctan(4/5)

x = 38.7°

Find the indicated probability.
Ksju [112]

Answer:

P(B) = 0.55

Step-by-step explanation:

Given

P(A\ or\ B) = 0.8

P(A) = 0.4

P(A\ and\ B) = 0.15

Required

Find P(B)

In probability, we have:

P(A\ or\ B) = P(A) + P(B) - P(A\ sd B)

Substitute values

0.8 = 0.4 + P(B) - 0.15

Collect Like Terms

P(B) = 0.8 - 0.4 + 0.15

P(B) = 0.55

VikaD [51]

Answer:

40+2s=60-3s

Step-by-step explanation:

The red balloon starts 40 feet off the ground and rises 2 feet per second. This means the height of the red ballon is 40+2s.

The blue balloon starts 60 feet off the ground at starts falling 3 feet per second. This means the height of the blue balloon is 60-3s.

Because we want to find out when the balloons will be the same height, we set them equal to each other.

40+2s=60-3s
