Answer:
<h2>FD = 26</h2>
<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
You're going to have to find the area of each individual box and then add so the very top box to find the area you would do 3×3×3 which equals 27 so the area of the top boxes 27 now we have to do the bottom box to you that you have to do 6×3×9×3
Answer:
510
Step-by-step explanation:
Assume 2 numbers 500,500.. with a mean of 500
so if we add 10 to each of the two numbers, mean will be:
Of course you can vary the set and the numbers and still get the same mean

Answer:
D 30
Step-by-step explanation:
each angle in the hexagon=120°
angleSMN=120°
all triangles =180° in total
180-120= 60
60÷2 =30
remaining 2 angles = 30° each
