Answer:
≈ 9.6 units
Step-by-step explanation:
<em>Refer to attachment</em>
The diagonal d is the hypotenuse of right triangle with sides of 5 and a
The line a is the hypotenuse of the right triangle with the sides of 2 and 8.
<u>So, as per Pythagorean theorem:</u>
- d² = 5² + a²
- d²= 5² + 2²+ 8² = 25 + 4 + 64 = 93
- d² = 93
- d = √93
- d ≈ 9.6 units (rounded to the nearest tenth)
