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.
x + 15 = 24
subtract 15 from both sides
x = 24 - 15 = 9
Answer:
u line ub the decimals and s=do regular subtraction
Step-by-step explanation:
Answer:
-8 = x
Step-by-step explanation:
-15 = 2x + 1
-1 - 1 Subtract 1 from both sides
-16 = 2x Divide both sides by 2
-8 = x
To make sure this answer is correct, plug it into the equation to see if it works.
-15 = 2(-8) + 1 Multiply
-15 = -16 + 1 Add
-15 = -15
Answer:
Any negative and positive number can be your coordinates.
Step-by-step explanation:
As long as you don't have any restrictions as to what the coordinates can be, you're good to go!
Hope this helps!
