Question

For the following right triangle, find the side length x. A=20 B=21

Answer 1

C = 29

Explanation:

using pythagoras theorem since the angle is a right angled triangle

it states that hypothenus²= opposite² + adjacent²

the hypothenus is always the longest side

opposite and adjacent are interwoven

hyp² = 20² +21²

hyp² = 400 + 441

hyp² = 841

hyp = √841 = 29

Answer 2

X equals 29 and you solve using the Pythagorean theorem
