Answer:
Step-by-step explanation:
Use a^2 + b^2 = c^2 to get the third side.
a = 12
b = ?
c = 37
a^2 + b^2 = c^2
144 + b^2 = 37^2
144 + b^2 = 1369 Subtract 144 from both sides.
<u>-144 -144</u>
b^2 = 1225 Take the square root of both sides
sqrt(b^2) = sqrt(1225)
b = 35
Perimeter = a + b + c
Perimeter = 12 + 35 + 37
Perimeter = 84
I don't get it. What do you mean. Sorry I couldn't answer it
