Question

angle XYZ is right angled at vertex X. If XY=15cm, ZX=20cm, find YZ​

Answer 1

Answer:

yz is hypotenuse

then 15 ka square + 20 ka square = yz ka square

225 + 400 = yz ka square

625 ka square root = yz

yz = 25

Answer 2

Answer:

25

by pythagoras theorem,( hypotenuse)^2=side^2+side^2

so,here hypotenuse=?

opposite side=15

Adjacent side=20

(hyp)^2=15^2+20^2

hyp^2=225+400

hyp^2=625

hyp=✓625

YZ=25.
