Answer:
a. = 36km
b. Perimeter = 108km
c. Area = 486km^2
Step-by-step explanation:
Pythagoras theorem
a^2 + b^2 = c^2
27^2 + b^2 = 45^2
b^2 = 45^2 - 27^2
b^2 = 1296
b =
b = 36km
Perimeter
a + b + c
27 + 36 + 45 = 108
Perimeter = 108km
Area =
Area =
Area =
Area = 486km^2
Answer:
the first one is 14 45
second one is 3 hours
lastly its 260km
Step-by-step explanation:
1 becuase u add 2 to 12 u get 14
2 u could do the same thing and minus them by each other to get the answer
and lastly u can multiply 65 by 4 and get the km

Answer: 108 degrees</h3>
Work Shown:
Let x and y be supplementary angles, which means they add to 180 degrees.
x = 72 is one of the angles. We don't know the other angle yet, so lets just keep it at y.
x+y = 180
72+y = 180 ..... plug in x = 72
72+y-72 = 180-72 ..... subtract 72 from both sides
y = 108
