D because there’s a pattern. Pattern for x is that it’s adding by one. Pattern for y is that it’s adding by 15
Let p be: John goes to the beach
Let q be: He will go surfing.
Then in symbolic form, the argument becomes:

p ⇒ q
p
---------------------
∴ q
An argument is valid if the conjuction of the premises implies the conclusion.
p | q | p ⇒ q | (p ⇒ q) ∧ p | [(p ⇒ q) ∧ p] ⇒ q
---------------------------------------------------------------------\
F | F | T | F | T
F | T | T | F | T
T | F | F | F | T
T | T | T | T | T
The table above shows that the argument is a tautology.
Hence, the argument is valid
E = 65° ( co-interior angle)
Angle F = 180-75 = 105°
Answer:
x = 9.75
Step-by-step explanation:
We know that Triangle ABC and DEF are congruent, therefore;
<em />

=> 12*x = 9*13
=> 12x = 117
=> x = 117 / 12
<u>=> x = 9.75</u>
Hope this helps!
