Answer:
∠ACD= 109°
Step-by-step explanation:
∠A=38
180- ∠A= ∠B+C
180-38= 2∠B( ∠B=∠C) ( angles opposite to equal sides are equal)
142=2∠B
∠B=71
∠ACD=∠A+∠B ( exterior angle property)
∠ACD= 38+ 71= 109°
519/6=86.5
915/7=130.7142
439/7=62.7142
812/9=90.2222
so i think its the 1st on but i may be wrong.
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>
