Step-by-step explanation:
Given,
y=2x=,z=3x,r=4x
Now,
x+y+z+r=360°(complete turn)
x+2x+3x+4x=360°(given)
10x=360°
x=360°/10
x=36°
Hence,
x=36°
y=2x=2×36°=72°
z=3x=3×36°=108°
r=4x=4×36°=144°
By rearranging x = 7y - 5 to make y the subject, we get
x + 5 = 7y ( By transposition method )
or, ![\huge \purple {\tt {\frac{x + 5}{7} = y}}](https://tex.z-dn.net/?f=%20%5Chuge%20%5Cpurple%20%7B%5Ctt%20%7B%5Cfrac%7Bx%20%2B%205%7D%7B7%7D%20%20%3D%20y%7D%7D%20)
