Question

Right triangle ABC (see top of right-hand column) has one leg of length 5 in. and a hypotenuse of length 13 in.
• a) Determine the length of the other leg.
• b) Determine the perimeter of the triangle.
• c) Determine the area of the triangle.

Answer 1

a 12
b 30
c 5 * 6 = 30

Answer 2

can you tell me how you got the answers?

Answer 3

ok
a pythagoras : x^2 = 13^2 - 5^2 = 144
x = 12
b 12+ 5 + 13 = 30
c area = 1/2 * base * height
= 1/2 * 12* 5
= 30

Answer 4

i din.t really do it this way because this is a 'pythagorean triad' - ie one of the right angled triangles with sides which are whole numbers
the first is 5,4,3
and next is 13,12,5

but my last post is general way to do these
