What is the length of CD ? In this diagram ABC EDC ?<br> Please help !!!!
n200080 [17]
Answer:
CD = x = 4 units

Explanation:
We are given that the two triangles are similar. This means that we can set the similarity proportionality as follows:
\frac{BC}{CD} =  \frac{CA}{CE} =  \frac{AB}{ED}

W e have:
BC = 20 - x
AC = 20
CD = x
CE = 5

Substitute in the above proportionality and solve for x as follows:
\frac{20-x}{x} =  \frac{20}{5} = 4

4x = 20 - x
5x = 20
x = 4

Based on he above:
CD = 4 units
BC = 20 - x = 20 - 4 = 16 units

Hope this helps :)

I don’t know how to solve this
Romashka-Z-Leto [24]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the length of all the sides in the figure.

The arc of the semi- circle is included in this.

length of arc = \frac{1}{2}πd ← d is the diameter

here d = 8, hence

arc = \frac{1}{2}π × 8 = 4π ← exact length

Perimeter = 10 + 8 + 10 + 4π ≈ 40.57 in ( nearest hundredth )
