2. Elena finds that the area of a house on a scale drawing is 25 square inches. The

likoan [24]

Answer:

The scale of the drawing is $\frac{1}{9}\ \frac{in}{ft}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of an house on a scale drawing in square inches

y ---> the actual area of the house in square feet

$z^2=\frac{x}{y}$

we have

$x=25\ in^2$

$y=2,025\ ft^2$

substitute

$z^2=\frac{25}{2,025}$

simplify

$z^2=\frac{1}{81}$

square root both sides

$z=\frac{1}{9}\ \frac{in}{ft}$

therefore

The scale of the drawing is $\frac{1}{9}\ \frac{in}{ft}$

What is the value of x? Enter your answer in the box. x

hram777 [196]

Answer:

Step-by-step explanation:

Use the triangle angle bisector theorem.

EG/GD = EH/HD

49/35 = 58.8/(x + 1)

49(x + 1) = 35 * 58.8

49x + 49 = 2058

49x = 2009

x = 41

Hope this helps!
