\frac{15}{4}  - 7x = 9 \\  \\   \frac{15}{4}  - 9 = 7x \\  \\ 7x =  \frac{15 - 36}{4}  \\  \\ 7x =  \frac{ - 21}{4}  \\  \\ x =  \frac{ - 21}{4 \times 7}  \\  \\ x =  \frac{ - 3}{4} .

How long is line UW?
Neko [114]

Answer: UW= 9√3

Step-by-step explanation:

This right triangle is a 30-60-90 triangle. This is a special triangle. Since this is a special triangle, the hypotenuse is 2x.

The hypotenuse is 18. We can figure out the length of x.

2x=18

x=9

Since we got 9, you would think it is the answer, but it's not. The length across the 60° angle is x√3. Now that we know the length across from 60°, we can plug in x.

9√3

We can check our answer by using Pythagorean Theorem.

9²+(9√3)²=18²

81+243=18²

324=324

Since they are equal, we know we have the right answer.
