Answer:

  y = 8√3

Step-by-step explanation:

In the 30°-60°-90° "special" triangle, the ratio of sides lengths is ...

  1 : √3 : 2 = 8 : y : hypotenuse

In order for these ratios to be equal, we must have ...

  y = 8√3

__

If you want to solve this using your trig skills, you recognize that ...

  Tan = Opposite/Adjacent

  tan(30°) = 8/y

  y = 8/tan(30°) . . . . where tan(30°) = 1/√3

  y = 8√3

Find the value of x, 110°, 4x+2, and if you can help with steps that would be great :,)
Helen [10]

Answer:

x = 17

Step-by-step explanation:

The two angles with measures form a linear pair and are supplementary.

The measures of supplementary angles has a sum of 180°.

If you add the two given measures, the sum must equal 180°.

4x + 2 + 110 = 180

4x + 112 = 180

4x = 68

x = 68/4

x = 17

PLEASE ANSWERRRRRRRRRRRRRRR
hoa [83]

Let T,S be the number of days spent at Tahoe and San Francisco, respectively.

We don't know the values of T and S yet, but we know that the holiday lasted 9 days:

T+S=9

We also know that each day spent in Tahoe costed 350 and each day spent in San Francisco costed 475. So, the total cost of the holiday is the sum of the number of days muliplied by their cost:

350T+475S=3650

If we put the two equations together, we have the system

\begin{cases}T+S=9\\350T+475S=3650\end{cases}

Which yields

S=4,\quad T=5
