Question

What is the value of c?

Answer 1

c = 5

Explanation:

ΔWYZ is a right triangle with ∠Y = 90° and WZ the hypotenuse

Using Pythagoras' identity on the triangle

c² = 3² + 4² = 9 + 16 = 25

⇒ c =
`√(25)` = 5

Answer 2

You have to use the Pythagoreas theorem where you do 3 squared + 4 squared=25
Then you square root 25 which is 5 so
c is 5
