Question

in a right angled triangle if lengths of hypotenuse and one of the legs are 29 cm and 21 CM respectively find the length of the other side​

Answer 1

Answer:

the length of other side will be 20cm

Step-by-step explanation:

You can use Pythagorean triplets or

Solve; By phythagoras theorem

Hypotenuse^2= Side opposite^2 + adjacent side^2

29^2 = 21^2 +adjacent side^2

29^2-21^2= adjacent side^2/other side

841-441=adjacent side^2/other side

which is equal to 400

taking square root of 400

we get 20cm

therefore the answer is 20CM

Answer 2

Answer:

hy = 29 cm

a = 21 cm

hy = √[a^2 + b^2]

29^2 = 21^2 + b^2

841 = 441 + b^2

√400 = b

b = 20 cm.
