Area of a triangle can be calculated in different ways.
The most used and "normal" way is:
(width * height) / 2
Another way is by using herons formula, which looks like this:
a, b, c = different sides
s = (a + b + c) / 2
a =

Option B.
Step-by-step explanation:
we know that
In a right triangle
because
Verify
The sine of angle x is equal to divide the opposite side angle x by the hypotenuse
The cosine of angle y is equal to divide the adjacent side to angle y by the hypotenuse
therefore
The ratios are both identical (5/13 and 5/13)
