Find the area of the composite figure(right triangle), where the hypotenuse is 13m, base is 12m and the height is not given?
3 answers
5^2 + height^2 = 13^2
Can you please explain this to me?
recall that if the legs of a right triangle are a and b, and the hypotenuse is c, then the Pythagorean Theorem states that
a^2 + b^2 = c^2
So, the height of the triangle is 12
There are several commonly used right triangles which you would do well to commit to memory:
3-4-5
5-12-13
7-24-25
and all multiples of them, such as
6-8-10, 9-12-15, ...
