Question

In the above figures, find the value of x​

Answer 1

Answer:

x = 6

Step-by-step explanation:

Using Pythagoras theorem, a² + b² = c² to find the value of x

x² + (4.5)² = (7.5)²

x² = (7.5)² - (4.5)²

x² = 56.25 - 20.25

x² = 36

x = √36

x = 6

Answer 2

Answer:

using Pythagoras theorem,

DF²=DE²+EF²

7.5²=x²+4.5²

56.25-20.25=x²

36=x²

x=6
