I have attached an image showing the triangle with angle and distance depicted in the question.

Answer:

151 miles

Step-by-step explanation:

We have to first find the unknown angle in the triangle.

Sum of angles in a triangle is 180°.

Thus, if we call angle at Norfolk A, we have;

A = 180 - (83 + 31)

A = 66°

Using sine rule, we can find the distance which we will term as a.

Thus;

a/sin 83 = 139/sin 66

a = (139 × sin 83)/sin 66

a = 137.963915/0.913545

a ≈ 151 miles

1 Determine Whether a Number Is a Solution to an Equation

An equation in one variable is a statement made up of two expressions that are equal, and in the statement, at least one of the expressions contains the variable. The expres- sions are called the sides of the equation. Examples of equations in one variable are

Answer:

Triangle a: 44.7°

Triangle b: 30.5°

Triangle c: 67.4°

Triangle d: 56.6°

Step-by-step explanation:

Recall: SOHCAHTOA

a. Reference angle = [tex] \theta [/tex]

Opposite = 19

Hypotenuse = 27

Apply SOH:

[tex] sin(\theta) = \frac{Opp}{Hyp} [/tex]

[tex] sin(\theta) = \frac{19}{27} [/tex]

[tex] \theta = sin^{-1}(\frac{19}{27}) [/tex]

[tex] \theta = 44.7 degrees [/tex] (nearest tenth)

b. Reference angle = [tex] \theta [/tex]

Opposite = 33

Adjacent = 56

Apply TOA:

[tex] tan(\theta) = \frac{Opp}{Adj} [/tex]

[tex] tan(\theta) = \frac{33}{56} [/tex]

[tex] \theta = tan^{-1}(\frac{33}{56}) [/tex]

[tex] \theta = 30.5 degrees [/tex] (nearest tenth)

c. Reference angle = [tex] \theta [/tex]

Opposite = 12

Adjacent = 5

Apply TOA:

[tex] tan(\theta) = \frac{Opp}{Adj} [/tex]

[tex] tan(\theta) = \frac{12}{5} [/tex]

[tex] \theta = tan^{-1}(\frac{12}{5}) [/tex]

[tex] \theta = 67.4 degrees [/tex] (nearest tenth)

d. Reference angle = [tex] \theta [/tex]

Hypotenuse = 20

Adjacent = 11

Apply CAH:

[tex] cos(\theta) = \frac{Adj}{Hyp} [/tex]

[tex] cos(\theta) = \frac{11}{20} [/tex]

[tex] \theta = cos^{-1}(\frac{11}{20}) [/tex]

[tex] \theta = 56.6 degrees [/tex] (nearest tenth)

a. 4!+3!
b. 4×3
c.4!×3!
d. 4!/3!

Total possible routes participants can choose = 4×3 = 12 ways

The correct option is - b. 4×3

Step-by-step explanation:

Given - A behavioral economist studies transportation habits in an

            urban center. She identifies 4 bus routes that connect to 3

            different light rail routes available to participants in the study.

To find - Before she interviews participants, she must determine the

              number of possible routes participants can choose to use.

              Which expression represents the number of available options.

Proof -

Given that ,

Total bus routes = 4

So, number of possible ways she use the bus route = 4

Also,

The 4 bus route connects to 3 different light rail

So, possible ways that she use light rail = 3

∴ we get

Total possible routes participants can choose = 4×3 = 12 ways

The correct option is - b. 4×3
