Answer:
Slope = -1
Step-by-step explanation:

Area of a triangle = 1/2 x base x height
Area = 1/2 x 8.7 x 8.6
Area = 37.41 square feet
Answer:
Step-by-step explanation:
the fare : 308
airport fee : 2 * 16 = 32 (because there is 2 airports)
tax on fare : 12
total is : 308 + 32 + 12 = $352 <==
The angle does not matter. Think of it as finding the other side to a triangle. Use

a=39 (line AB)
b=b (the leg we need to find)
c=89 (line BD)


(subtract the 1521 from both sides)

(square root both sides)

b = 80
AD=80
Answer:
