Answer:

b = 30 km is the answer

Step-by-step explanation:

a = 72 km

b = ?

c = 78 km

According to the Pythagoras theorem,

a² + b² = c²

72² + b² = 78²

5184 + b² = 6084

b² = 6084 - 5184

b² = 900

b = 30 km

∴ b = 30 km is the length of the missing leg

-6 = n/2 - 10 show work
valina [46]

Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 10 to both sides

-6 (+10) = n/2 - 10 (+10)

10 - 6 = n/2

4 = n/2

Next, isolate the n. Multiply 2 to both sides

4(2) = n/2(2)

n = 4(2)

n = 8

8 is your answer

hope this helps
