Length of third side

Answer:
x=-1
Step-by-step explanation:
Slope = difference in y / difference in x
Slope = (w --9) / (5 --7)
Slope = (w +9) / (5 + 7)
12 * slope = w +9
w = 12*slope -9 and since slope = 1,
w = 12 -9
w = 3
Answer:
A = 18
sq meters
Step-by-step explanation:
find BD, can use altitute rule:
3 / BD = BD / 9
BD² = 27
BD =
= 3
Area of ΔABC = 1/2 · (3+9) · 3
A = 6 · 3
