The perpendicular bisector of the segment passes through the midpoint of this segment. Thus, we will initially find the midpoint P:

Now, we will calculate the slope of the segment support line (r). After this, we will use the fact that the perpendicular bisector (p) is perpendicular to r:


We can calculate the equation of
p by using its slope and its point P:
Answer:
35
Step-by-step explanation:
1. Translate the question into an equation:
2. Multiply both sides by 7/4.
Answer:
9
Step-by-step explanation:
To calculate c from the first right angle triangle,
C2 = 36 + 16
C = sqrt(52)
To calculate a from the bigger right angle triangle,
B2 + 52 = (a + 4)2
B2 - a2 = -36 + 8a
A2 + 36 = B2
Solving both by elimination,
A = 72/8
