Step-by-step explanation:

Similar Triangles

By looking at the construction of the figure, we can safely assume both triangles are similar, i.e. their internal angles are equal and their sides are proportional. Following the proportion of the heights and bases of both triangles we can set this relationship:

$\displaystyle \frac{45}{36}=\frac{5x}{20}$

Simplifying both fractions

$\displaystyle \frac{5}{4}=\frac{x}{4}$

Solving for x

$x=5$

The area of circle Z is 64. What is the value of r? r = ____ft

andrezito [222]

Given the circle has a radius of 64, to get the value of the radius,r we shall proceed as follows.
Area=πr^2
Thus;
64=πr^2
64/π=r^2
r^2=20.3718
r=sqrt(20.3718)
r=4.5135
Therefore the length of radius,r=4.5135 units
