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}

Area and perimeter of geometric functions
SCORPION-xisa [38]

Answer:

C. 60

Step-by-step explanation:

From triangle ADB,

|AD|^2+|BD|^2=|AB|^2

|AD|^2+16^2=20^2

|AD|^2=20^2-16^2

|AD|^2=400-256

|AD|^2=144

|AD|=\sqrt{144}

|AD|=12

From triangle ADC,

|CD|^2+12^2=15^2

|CD|^2+144=225

|CD|^2=225-144

|CD|^2=81

|CD|=9

The perimeter is the distance around the figure.

The perimeter

=15+20+16+9

=60
