The legs of a right triangle are 3 units and 8 units. What is the length of the hypotenuse? Round your answer to the nearest hun

Alisiya [41]

Answer:

<h2>8.54 units</h2>

Step-by-step explanation:

Given,

Perpendicular ( p ) = 8 units

Base ( b ) = 3 units

Hypotenuse ( h ) = ?

Using Pythagoras theorem:

${h}^{2} = {p}^{2} + {b}^{2}$

plug the values

${h}^{2} = {8}^{2} + {3}^{2}$

Evaluate the power

${h}^{2} = 64 + 9$

Calculate the sum

${h}^{2} = 73$

Squaring on both sides

$h = \sqrt{73}$

Calculate

$h = 8.54$ units

Hope this helps..

Best regards!
