Answer:

Exact: 3,999,500,000

Estimate: 4,000,000,000

Step-by-step explanation:

(4)(10) = 40

(4 x 10)9 = 4,000,000,000

Notice that there are 9 zeros

_________________________________________

(5)(10) = 50

(5 x 10)5 = 500,000

Notice that there are 5 zeros

_________________________________________

4,000,000,000 - 50,000 = 3,999,500,000

Right triangle ABC is similar to triangle XYZ. If the length of side AB is 20.8 units, the length of side BC is 36.4 units, and

trasher [3.6K]

Answer:

XY is 4 units.

Step-by-step explanation:

We are given the following in the question:

Right triangle ABC is similar to triangle XYZ.

AB = 20.8 units

BC = 36.4 units

YZ = 7 units

We have to find the length of side XY.

Since the given triangles are similar, they have the following property:

The ratio of corresponding sides of similar triangles are equal.

We can write,

$\displaystyle\frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}$

Putting the given values, we have,

$\displaystyle\frac{AB}{XY}=\frac{BC}{YZ}\\\\\frac{20.8}{XY}=\frac{36.4}{7}\\\\XY = \frac{20.8\times 7}{36.4} =4 \text{ units}$

Thus, the length of XY is 4 units.
