Answer:
z = 5.5
Explanation:
According to Pythagorean theorem, the square value of hypotenuse is equal to the sum of square value of legs.
To find the length of z we can write the following equation based on above mentioned information:
(6.4)² = z² + (3.2)²
- Calculate the square values.
40.96 = z² + 10.24
- Subtract (10.24) from both sides.
30.72 = z²
- Find the root of both sides.
5.5 = z
