`Delta xyz`में,` /_x=45^@` और `/_y=75^@,/_z` ज्ञात कीजिय |

If x + y + z = 10, x^3+y^3+z^3=75 and xyz = 15, then find the value of x^2+y^2+z^2 -xy-yz-zx यदि x + y + z = 10, x^3+y^3+z^3=75 तथा xyz = 15 है, तो x^2+y^2+z^2 -xy-yz-zx का मान ज्ञात कीजिए।

In /_\XYZ , /_X=30^@ , /_Y=45^@ then find /_Z =

In triangle XYZ, /_Y=90^@, /_Z=a^@, /_X=(a+30)^@ . If XZ=24 , find XY and YZ .

If x+y+z = 400 and x:y:z = 1:1:2. Then find the value of z ? यदि x+y+z = 400 तथा x:y:z = 1:1:2 है, तो z का मान ज्ञात करें ।

If x = 255, y = 256, z = 257, then find the value of x^3+y^3+z^3-3xyz . यदि x = 255, y = 256, z = 257 है, तो x^3+y^3+z^3-3xyz का मान ज्ञात कीजिए ।

If x+y+z=2, xy+yz+zx=-11, then the value of x^3+y^3+z^3-3xyz is : यदि x+y+z=2, xy+yz+zx=-11 है ,तो x^3+y^3+z^3-3xyz का मान ज्ञात करें |
