X=7
Explanation:
A triangle equals 180°, and they gave us one length already, and it says the one arm of the triangle is equal to the other so we know that the third angle is going to be the same as the second angle.
180=90+(6x+3)+(6x+3)
Combine like terms
180=96+12x
Subtract 96 from both sides
84=12x
Divide 12 by both sides
7=x
Now check it,
90+(6*7+3)+(6*7+3)
90+(45)+(45) =180
I don’t now what the answer is sorry I will try and figure it
when "If P, then Q" is true, "if not Q, then not P¨ is also true.
So the given statement is true.
<h3>
The statement is true or false?</h3>
Let's suppose we have a conditional statement:
If P, then Q.
That is true.
The statement says that:
If not Q, then not P.
Is also true.
Now, let's go to the original conditional statement.
"If P, then Q"
This means that always that P is true, then Q must also be true. But we can have cases where P is false and Q is true. (this means that Q can't be true if P is not true).
Now, if we affirm that Q is false (or not Q is true, these are the same thing). Then we must have that P is also false (or not P is true).
So the given statement is true.
when:
If P, then Q
is true.
if not Q, then not P¨
is also true.
