Answer:
Explanation:
The third side of the triangle may be found using Pythagoras theorem.
Pythagoras theorem is for right angle triangles-
c^2 = a^2 + b^2
‘c’ = the side opposite the triangle’s 90 degree angle. This is called the hypotenuse.
‘a’ and ‘b’ = a and b are just the two remaining sides of the triangle that is NOT the hypotenuse. It does not matter which side you pick out of the two for ‘a’ and which side you pick for ‘b’
The side we are trying to find is the hypotenuse, which is ‘c’
Let’s say that
a= 9m
b= 12m
Substituting that into the
c^2 = a^2 + b^2 formula,
c^2 = 9^2 + 12^2
= 81+ 144
= 225
( square root both sides of the equation so we get just the value of ‘c’)
c= 15m
Therefore the missing side (the right angle triangle’s hypotenuse) is 15m.
