We know that ∠1 equals ∠3, from that we can find x:

10x = 100 \\ x = 10

The sum of ∠1 and ∠2 must equal 180°:

10x + 10y + 20 = 180

Since we already know x, we can solve for y:

10 \times 10 + 10y + 20 = 180 \\ 10y + 120 = 180 \\ 10y = 60 \\ y = 6

Result: x=10, y=6

Which of the following properties is represented by (ab)c = a(bc)?
DochEvi [55]

Answer:

Associative Property of Multiplication

Step-by-step explanation:

We are given three numbers-a,b,c.

We are given the property (ab)c = a(bc)

This implies that on the left hand side we first multiply a and b and then multiply the result by c. On the right side of the equation, we first multiply b and c and multiply a with the product of b and c.

As per the given property, the result in both the cases is the same.

This signifies the associative property of multiplication where the result is independent of the order of operation.
