Question

Find the length of the missing side. Leave your answer in simplest radical form.

Answer 1

Answer:

Step-by-step explanation:

So, we use the formula -  

hypotenuse^2 = side1^2 + side2^2

==> hypotenuse^2 = 4^2 + 3^2

==> hypotenuse^2 = 16 + 9

==> hypotenuse^2 = 25

==> hypotenuse = square root (25)

==> hypotenuse = 5

Answer 2

Since it is a right angled triangle, Pythagorean theorem will be applied to it to calculate the hypotenuse (missing side of the triangle). 

So, we use the formula - 
hypotenuse^2 = side1^2 + side2^2
==> hypotenuse^2 = 4^2 + 3^2
==> hypotenuse^2 = 16 + 9
==> hypotenuse^2 = 25
==> hypotenuse = square root (25)
==> hypotenuse = 5

So, the final answer is --> the length of the missing side = 5
