a^2 + b^2 = c^2.....a and b are the legs and c is the hypotenuse

so u would use : 20^2 + 21^2 = 29^2

Answer:

B .\((20)^2+(21)^2=(29)^2\)

Step-by-step explanation:

We are given that

Three sides of given triangle are 21, 20 and 29.

If a triangle is right triangle, the triangle satisfied the pythagorous theorem.

Pythagorous theorem:

\((hypotenuse)^2=(base)^2+(Perpendicular\;side)^2\)

\((29)^2=841\)

\((20)^2+(21)^2=400+441=841\)

Hence , \((29)^2=(20)^2+(21)^2\)

Answer: B .\((20)^2+(21)^2=(29)^2\)
