Use Pythagorean theorem to decide which of these measures would be correct for the lengths of the sides of a right triangle.

blagie [28]

Answer: D) 9, 12, 15

Step-by-step explanation:

The side lengths need to satisfy the Pythagorean theorem, $a^{2}+b^{2}=c^{2}$

A) $2^{2}+3^{2}=4^{2} \longrightarrow 13=16$ , which is false.

B) $7^{2}+11^{2}=14^{2} \longrightarrow 170=196$ , which is false.

C) $8^{2}+10^{2}=12^{2} \longrightarrow 164=144$ , which is false.

D) $9^{2}+12^{2}=15^{2} \longrightarrow 225=225$ , which is true.

An issue of Taunton's Fine Woodworking included plans for a hall stand. The total height of the stand is 5912 59 1 2 inches. If

evablogger [386]

The length if the upper portion of the stand is 33. 56 inches

<h3>How to determine the length</h3>

The formula for the finding the length is given thus;

Total height = length of upper portion + length of base

Where

Length of base = 257/16

Total height = 591/2

Length of upper portion = total height - length of base

= 118/2 - 407/16

= 59 - 25. 44

= 33. 56 inches

Thus, the length if the upper portion of the stand is 33. 56 inches
