C
Step-by-step explanation:
First check if the triangle is right.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side =
and (
)² = 12

Answer:
a = 180 - 92 - 27=61
b = 92 + 27= 119
Step-by-step explanation:
The answer would be A-72cm^2
Commutative property of addition is
a+(b+c)=(a+b)+c
so just move the partenthsees ()
(1 5/8+4 3/4)+3 2/8=1 5/8+(4 3/4+3 2/8)
