Answer:

$x=5,\\AC=14$

Step-by-step explanation:

Since one triangle is inscribed in another, the two triangles are similar. As marked in the diagram, the sides of the larger triangle are exactly two times larger than the corresponding sides of the smaller triangle.

Therefore, we have:

$2(x+2)=4x-6,\\2x+4=4x-6,\\10=2x,\\x=\boxed{5}$

Since AC is marked by $4x-6$ :

$AC=4(5)-6,\\AC=20-6,\\AC=\boxed{14}$

mars1129 [50]

Answer:

Option A $95\ ft$

Step-by-step explanation:

we know that

$1\ ft=12\ in$

The height of the player is $6\ ft\ +4\ in$

$6\ ft\ +4\ in=6*12+4=76\ in$

by proportion

$\frac{4}{5} \frac{in}{ft}=\frac{76}{x}\frac{in}{ft}\\ \\x=5*76/4\\ \\x=95\ ft$

What is the area, in square units, of the polygon shown here?

Molodets [167]

The area of a 2D form is the amount of space within its perimeter. The correct option is D.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The area of the L block will be the sum of the area of A and B. Therefore, the area can be written as,

Area of L block = Area of A + Area of B

= (7×2) units² + (1 × 5) units²

= 14units² + 5units²

= 19units²

Hence, the correct option is D.
