This is a right triangle. We know that

                                                  \sin x = \frac{\text{opposite side}}{\text{hypotenuse}}

Therefore,

                                            \sin x = \frac{15}{20} = \frac{3}{4} = 0.75

Now we have:

                                                    x=\sin^{-1}0.75

                                                         x=48.6

A farmer is designing a field for his new horse. In order for the field to fit into his farm, the angle θ must be less than 40◦,
vovangra [49]

Answer:

The field will not fit

Step-by-step explanation:

To find the angle, we will use cosine rule;

c² = (a² + b² - 2abcosC)

C in this case is θ

Thus;

15² = (8² + 20² - 2(8 × 20)cos θ)

225 = (64 + 400 - 320cos θ)

464 - 225 = 320cos θ

cos θ = 239/320

θ = cos^(-1) 0.7469

θ = 41.68°

Thus angle is not less than 40° as recommended. Thus, the field will not fit.

Triangle GHI is translated using the rule (x, y) → (x + 5, y) to create triangle G′H′I′. If a line segment is drawn from point G
Debora [2.8K]

Step-by-step explanation:

the second answer.

they are parallel and congruent (same length).

simply because both points were translated by adding the same number of units to x. so, they have the same length, and point in the same direction.

you have a big bag of 17 marbles for our blue sticks are green 2 are red and the others are yellow what is the probability of dr
Alex Ar [27]

Answer:

  • 3/68

Step-by-step explanation:

<u>Given</u>

  • Total 17 marbles
  • 4 - blue marbles
  • 6 - green marbles
  • 2 - red marbles
  • The rest - yellow marbles

<u>Probability of drawing red first:</u>

  • P(red) = number of red / total number = 2/17

<u>Probability of drawing green second, without replacement:</u>

  • P(green) = number of green / number left in the bag = 6/16 = 3/8

<u>Probability of red and green in order:</u>

  • P = P(red)*P(green) = 2/17*3/8 = 3/68
