Question

If y/x = 5 and z/x= 4, where x, y and z are the angles of triangles. Then the
value of x is:

Answer 1

Answer:

x,y,z are angles of triangle

x+y+z = 180. ....(1)

y/x = 5. ....(2)

and, z/x = 4

$\frac{180 - x - y}{x} = 4$

or, 180-x-y = 4x

or, 180-x-5x =4x. from(2)

or, 10x = 180

or, x = 18 and y = 90 and z = 72
