Answer:
978 in
Step-by-step explanation:
(9x6)+(18x18)+(25x24)=978
Supplementary means it adds up to 180 degrees.
So if one side is 31 degrees, you would need to subtract that from 180 to find the other side.
-----------------------
180 - 31 = 149
-----------------------
The other angle would be 149 degrees.
Answer:
459
Step-by-step explanation:
because 3^5 is 243 and 6^3 is 216 then add up 243+216=459
Perimeter is adding all the sides.
since it is square it is 14 +14 +14 +14 = 56 miles
