Answer: If a quadrilateral is a square, then it is a rectangle. (choice D.)
Step-by-step explanation:
The Law of Syllogism states that if the following two statements are true: If p , then q . If q , then r . Then we can derive a third true statement: If p , then r .
We can apply this rule in the conditional statements:
<em>If a quadrilateral is a square, (p) then it has four right angles. (q)</em>
<em>If a quadrilateral has four right angles, (q) then it is a rectangle. (r)</em>
Therefore:
<em>If a quadrilateral is a square, (p) then it is a rectangle. (r)</em>

Answer:

Step-by-step explanation:
we know that
In the right triangle of the figure
The cosine of the angle of 35 degrees is equal to divide the adjacent side to the angle of 35 degrees by the hypotenuse
so
-----> by CAH
solve for x


It’s -4 because when you take 4 out of 8 then you still have another 4 to take away to you go into the negatives and have the answer -4
Convert percent to decimal by moving the percent sign two places to the left.
12% => 0.12
'Of' in math means multiply: 0.12 * 30 = 3.6
3.6 is the answer.
