Question

If y=
5X and Z=
4x, then Value
of X ​

Answer 1

Answer:

x = 18°

Step-by-step explanation:

x° + y° + z° = 180° [ Linear pair angles ]

x° + 5x° + 4x° = 180°             { y = 5x ; z = 4x}

10x° = 180°

x = 18°

                         

Answer 2

Answer:

Step-by-step explanation:

Y = 5x

z = 4x

x + 5x + 4x = 180° (straight line)

10x = 180°

x = 180/10

x = 18°

y = 5x

y = 5(18) = 90°

z = 4x

z = 4(18°) = 72°

so x = 18° , y = 90° , z = 72°

proof : 18 + 90 + 72 = 180°

proof is only for checking whether the answer is correct
