A same side interior angle of two parallel lines is five times smaller than the other same side interior angle. Find the measures of these two angles.

30°  and 150°

Step-by-step explanation:

Let the smaller side is x then other side is 5x,

x+5x=180°[interior property]

on solving we get

6x=180°

x=30°

therefore the other side is 5x=5*30°=150°

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
