For the following right triangle, find the side length x. a=20 b=21

C = 29

Step-by-step 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

109 is the nearest whole number/final answer! : )

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
