337.5 is the distance (d) and 4.5 is the time (t)
to find r it is d/t, so 337.5÷4.5 is 75mph so the answer is c

r =  \frac{337.5}{4.5}  \\ r = 75
the answer is c-75mph

Solve for x to the nearest degree (34.3 = 34)
Hoochie [10]

Answer:

48°

Step-by-step explanation:

We can solve this using our knowledge on tangents of an angle. Remember, tangents are the opposite leg divided by the leg adjacent to that angle.

This means the tangent of x° =  \frac{10}{9}. Now that we know the tangent ratio, we can find the angle with inverse trigonometric ratios. These kinds of ratios give us the opposite of the tangent - which would lead to the angle measure we're looking for. The equation would look like this:

x = arctan (\frac{10}{9})

Using a calculator, the answer would be:

x = 48.0128

Rounding this to the nearest degree would give us 48° as our answer! I hope this was clear enough.

A particular airport has beacons on the ground 6 km out from the start of each runway. An airplane is directly over this beacon
hodyreva [135]

Answer:

6.06 km

Step-by-step explanation:

The information given in the question can be represented by the three sides if a right angled triangle.

Let the direct line from the airplane to the start of the runway be represented by x. So that applying the appropriate trigonometric function, we have;

Cos θ = \frac{adjacent}{hypotenuse}

Cos 8^{o}  = \frac{6}{x}

0.9903 = \frac{6}{x}

⇒ x = \frac{6}{0.9903}

      = 6.0588

x = 6.06 km

The direct line from the airplane to the stat of the runway is 6.06 km.
