Answer:
length of CD = 18 units.
Step-by-step explanation:
In ΔABC and ΔCED,
AB║DE and AD is a transversal line,
m∠ABC = m∠CED [Alternate interior angles]
m∠ACB = m∠DCE [Vertically opposite angles]
ΔABC ~ ΔCED [By AA property of similarity]
Therefore, by the property of similar triangles, corresponding sides will be proportional.


CD = 6
Since, AD = AC + CD
AD = 12 + 6
= 18 units
Therefore, length of CD = 18 units.

The suquare root is 10. it is a rational number
Answer:
33°
Step-by-step explanation:
From SOH CAH TOA
Sin X = 12/22
X= sin-1 (0.545)
X=33°
They are actually the same.....Hope this helped you!!
