Answer:

A) AA postulate; 18

Step-by-step explanation:

Due to the similar triangles, we can set up the proportion and solve for x

8/(8+4) = 12/x

8/12 = 12/x

8*x = 12*12 ... cross multiply

8x = 144

x = 144/8

x = 18

Step-by-step explanation:

we know that

To know how much material Marco will need to make the kite, the area must be calculated.

Remember that the area of the kite is equal to

$A=\frac{1}{2}[d1*d2]$

where

d1 and d2 are the diagonals of the kite

we have

$d1=2\ ft$

$d2=3\ ft$

substitute

$A=\frac{1}{2}[2*3]=3\ ft^{2}$
