Answer:
80
Step-by-step explanation:
The opposite angles in a cyclic quadrilateral are supplementary. The sum of the opposite angles is equal to 180˚
x+100=180
x=180-100=80
Answer:
1200 seats
Step-by-step explanation:
<u> x </u> = <u> 660 </u>
100 55
55x = 66,000
x = 1200
Answer: 12?
Step-by-step explanation:
The area of a triangle is half the product of the base and the height.
Since multiplication is commutative, the following expressions are equivalent:

So, option D is correct
Answer:
Associative property: a + (b + c), a – (b – c) ≠ (a – b) – c, a × (b × c) = (a × b) × c, and a ÷ (b ÷ c) ≠ (a ÷ b) ÷ c
When a = ½ and b = ¾
Now, for checking a × b = b × a, consider LHS and RHS.
LHS = a × b = ½ × ¾ = ⅜
RHS = b × a = ¾ × ½ = ⅜
Thus, LHS = RHS (Hence proved)
