For this case we have the following equation:

\frac {3} {4} = \frac {2} {v-2}

Resolving we have:

3 (v-2) = 2 * 4\\3 (v-2) = 8

We apply distributive property to the terms of parentheses:

3v-6 = 8

Adding 6 to both sides of the equation:

3v = 8 + 6\\3v = 14

Dividing between 3 on both sides of the equation:

v = \frac {14} {3}

ANswer:

v = \frac {14} {3}

Answer:

4. x = 16.8

5. x = 35.98

Step-by-step explanation:

For both triangles that you need to work on, use the trigonometric function which is tan and you are dividing opposite by adjacent for the answers.

For number 4, the equation you are setting up is tan 35 = x/24.  Multiply 24 on both sides to get the answer which is 16.8 for the x side.

For number 5, the equation you are setting up is tan 17 = 11/x.  As a result on your calculator, you should get 35.98 for the x side.
