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.
Answer:
b = 2A/h
Step-by-step explanation:
The formula for area of a triangle is
A = 1/2 bh where b is the base and h is the height
We want to find the base
Multiply each side by 2
2A = 2*1/2 bh
2A = bh
Divide each side by the height
2A/h = bh/h
2A /h = b
b = 2A/h
The sign should be changed as well
Answer:
