Answer:
C.
Step-by-step explanation:
When two polygons are considered similar, the ratio of their corresponding sides would also be equal.
Since ∆ABC and ∆ADE are similar,
Cross multiply
Divide both sides by 7 to find AB

Answer:
1/2 + 3i is the midpoint between -2-3i and 3+9i.
Step-by-step explanation:
Given the complex number
- -2-3i
- 3+9i
The formula to find the midpoint of two complex number (a + bi) and (c + di) is:
Therefore, 1/2 + 3i is the midpoint between -2-3i and 3+9i.
The slope of the perpendicular line will be 2. Remember, a perpendicular slope is the negative reciprocal.
So, we can make the equation . We need to find b, and put b in.
To find b, put in the numbers of y and x.
Solve for b:
Now replace b in the original equation with 12 and that will be the answer:
The answer is .
