By applying Cathetus theorem, the value of x is equal to 10 units.
<h3>How to determine the value of x?</h3>
In order to determine the value of x, we would apply Cathetus theorem (leg rule), which states that each leg of a right-angled triangle is the geometric mean that's directly proportional between the hypotenuse and the part of the hypotenuse that's directly below the leg.
In this context, we have:
x² = m × a
x² = (21 + 4) × 4
x² = 25 × 4
x² = 100
x = √100
x = 10 units.

Step-by-step explanation:
Answer:
400
Step-by-step explanation:
6/8 = 0.75 or 75% expected to respond favorably.
Margin of error 2.5%:
Lower bound: 0.75 - .025 = 0.725
Upper bound: 0.75 + .025 = 0.775
Range:
Lower bound: 8000 * 0.725 = 5800
Upper bound: 8000 * 0.775 = 6200
6200 - 5800 = 400
