Since ΔABC ~ ΔEDC, ∠B = ∠D.

Since both triangles appear to be similar, the corresponding angles are the same, and corresponding sides are the same or have the same ratio.

We can write an equation to resemble the problem:

8x + 16 = 120

Solve for x.

8x + 16 = 120

~Subtract 16 to both sides

8x + 16 - 16 = 120 - 16

~Simplify

8x = 104

~Divide 8 to both sides

8x/8 = 104/8

~Simplify

x = 13

Therefore, the answer is 13.

Best of Luck!

Volume=<br> A) 91 2/3 pie cubic units <br> B) 275 pie cubic units <br> C) 36 2/3 pie cubic units

MrMuchimi

the volume is 1/3 * height *area of the base (the circle) in cubic units

the area of the circle is pi*r²

wich gives us

1/3 * 11 * pi * 5²

rearrange

= 5² * 11 * 1/3 * pi

= 25*11*1/3*pi

= 275*1/3*pi

= 275/3 *pi

= (91 2/3)*pi

in cubic units

so your answer is the first option

Compare 6.23x10^14 and 8.912x10^12

Tju [1.3M]

Answer:

hello : 6.23x10^14 > 8.912x10^12^12

Step-by-step explanation:

let : A= 6.23x10^14 and B = 8.912x10^12

A= (6.23x10^2) x10^12 ... because : 10^14 = 10^2x10^12

A = 623 x 10^12

623 > 8.912

so : A > B
