1) Antonio's statement
2) <A = 123
Step-by-step explanation:
1) Antonio's statement is incorrect. This is because the opposite angles of a quadrilateral add up to 180°. Erin was incorrect because the opposite angles of this quadrilateral are unequal.
2) 2x+7+5x-2 = 180° (opposite angles of quadrilateral)
Now
7x+5 = 180
7x = 175
x = 25
<A = 5x-2
= 5(25)-2
= 125-2
= 123
Since the <span>sides of a square aretwo to the power of four ninths inches long.
</span>
Therefore, it can be written as :
The side of the square =
Now, area of square = (side)*(side) =
Area, A =
or A =
You would multiply the -7 by 3 to come up with -21/18.
