Answer:
C
Step-by-step explanation:
∠2 and ∠7 are alternate interior angles
alternate interior angles are congruent meaning ∠2 ≅ ∠7
we have ∠2 = 2x + 7 and ∠7 = 3x - 13
hence, 2x + 7 = 3x - 13
==> add 13 to both sides
2x + 20 = 3x
==> subtract 2x from both sides
20 = x
now to find the measure of ∠7 we plug in the value of x
∠7 = 3x - 13
==> plug in x = 20
∠7 = 3(20) - 13
==> multiply 3 and 20
∠7 = 60 - 13
==> subtract 13 from 60
∠7 = 47
Answer:
98.75%.
Step-by-step explanation:
On March 20, 2011, a $1000 bond had a selling price of $987.50.
We are asked what will be the quoted price for the bond.
Now, the quoted price of a bond is the price at which the bond was last traded and it is expressed as the percentage of the original bond value.
So, in our case the quoted price will be 
%. (Answer)

Step-by-step explanation:
A counterexample shows that one side is true while the other is false
x>7 and x>11
sub in the answers
9>7 and 9>11 -this is true for the first half but false for the second
5>7 and 5>11 -this is false for both
13>7 and 13>11 -this is true for both
15>7 and 15>11 -this is true for both
Answer A is correct as it proves the statement to be incorrect
Answer:
tan R= 45/28
tan S= 28/45
Step-by-step explanation:
tan R = TS/RT= 45/28
tanS = RT/TS= 28/45
