Answer:

<u>Step-by-step explanation:</u>

CD = ED --- (secant<em> </em>property<em>)</em>

so, ==>>

13x - 16 = 4x + 11

13x - 4x = 11 + 16

9x = 27

x = 27÷9

x = 3

side ED = 4x + 11 = 4×3 + 11

side ED = 23

side FE = 12

ΔFED = 90° ...... (tangent secant property)

so.........

FE² + ED² = FD² ......... ( by pythagoras theorm)

12² + 23² = FD²

144 + 529 = FD²

673 = FD²

√673 = FD

26 = FD

Answer:

Step-by-step explanation:

First distribute the 2x to get:

4x² + 10x

Then distribute the -5 to get:

-10x - 25

Then combine

4x² + 10x - 10x - 25

The 10x's will cancel leaving you:

4x² - 25

I think this is trying to represent the degrees of a pie chart.

To find the degree of the pi chart per person you need to 72/12=6

Than to find the amount of degrees per subject multiply 6*amount of students.

Example:

$6 \times amoumt \: of \: students \:taking \: music = 6 \times 18 = 108$
