Hi there!
We can begin by multiplying by its conjugate:
Simplify using the identity:
Take the square root of the expression:
Multiply again by the conjugate to get a SINGLE term in the denominator:
Simplify:
Use the above trig identity one more:
Cancel out sinA:
Split the fraction into two:
Recall:
Simplify:

If it's multiplication, it's 7/500. The reason being that Mark forgot to simplify.
B, just because the diagonals are perpendicular doesn't mean they are equal in length, you can get a Kite with perpendicular diagonals
The term that best describes the given statement above is the third option which is negation. In geometry, a negation statement is the opposite of a given mathematical statement. If a statement is true, then its negation is false. And if a statement is false, then its negation is true. The given statement above is false, therefore, it is a negation of the true statement.
