Answer:
The value of x = 24.4 units.
Step-by-step explanation:
Given
- a = 14
- b = 20
- c = x
For a right-angled triangle with sides a and b, the hypotenuse c is defined as
substituting c = x, a = 14 and b = 20
units
Therefore, the value of x = 24.4 units.
The length of other leg is 60 units.
Step-by-step explanation:

Length of one leg = a = 45 units
Length of other leg = b
Length of hypotenuse = c = 75 units
Using pythagoras theorem
Taking square root on both sides
The length of other leg is 60 units.
