Answer:

7√3 = x

Step-by-step explanation:

Arbitrarily choose to focus on the 30 degree angle.  Then the side opposite this angle is 7 and the side adjacent to it is x.

tan 30 degrees = (opp side) / (adj side), or (1√3) = 7 / x.

Inverting this equation, we get √3 = x/7.

Multiplying both sides by 7 results in 7√3 = x

Answer:

x =7\sqrt{3}

Step-by-step explanation:

By definition, the tangent of a z-angle is defined as

tan(z) =\frac{opposite}{adjacent}

For this case

opposite = 7

adjacent = x

z=30\°

So

tan(30) =\frac{7}{x}

x =\frac{7}{tan(30)}

x =7\sqrt{3}

You can ride a bicycle 15 mph. Your sister
igor_vitrenko [27]

Answer:

4

Step-by-step explanation:

Find the LCM of 12 and 15.

LCM = 60.

Now divide the LCM by the two numbers.

60/12 = 5, 60/15 = 4.

As the sister got an hour head start, subtract one.

5-1=4.

Therefore it will be 4 hours.
