Question

Find the missing side of a right angled triangle, using Pythagoras property

a) 9
b) 1
c) 3
d) 10

Answer 1

Step-by-step explanation:

Formula = c² = a² + b²

so,

5² = 4² + x²

25 = 16 + x²

25 - 16 = x²

9 = x²

x = √9

x = 3

Answer 2

Answer:

A²+B²=C²

(4²)+(x)²=(5²)

16+x²=25

x²=25-16

x²=9

x=√9

x=3
