let's recall that a triangle has a total of 180° for its interior angles.
x = first angle
3x = second angle, three times the first one
5x = third angle, five times the first one, and largest.

Answer:
81π
Step-by-step explanation:
-The sum of central angles in a circle add up to 360°.
-Let x be the area of the circle.
-Given the area of a 120° is 27π, the circles area can be calculated as:

Hence, the area of the circle is 81π
Answer:
Commutative property of multiplication.
Step-by-step explanation:
This property says that changing the order of factors doesn't change the product.
Here 5×3 will be 15..... If we interchange the places of 3 & 5 , still then the product will remain same i.e. 3×5 = 15
