Answer:

x = 12

Step-by-step explanation:

We have a right triangle with hypotenuse 10 and the height 8.  Either the one on the left or the one on the right

We can find the base using the Pythagorean theorem

a^2 + b^2 = c^2

a^2 +8^2 = 10^2

a^2  +64 = 100

Subtract 64 from each side

a^2 = 100 -64

a^2 = 36

Take the square root of each side

a = 6

Now a is 1/2 of the total base of the big triangle.  It is identical since the triangles are equal

x = 2 * a

x = 2*6 = 12

adoni [48]

Cost of the 3 shirts before  tax = 2*49.96 + 1/2 * 49.96

= $124.90

After adding 7.1% tax total cost  = 124.90 * 1.071 = $133.77

So the cost od each shirt = 133.77 / 3 = $44.59  (answer)
