Expert Answer
x+20 and 3x-60 are alternate angles formed due to intersection of line P with parallel lines l and m
x+20 = 3x-60 ;
By solving above expression , we get x = 40 .
---------------------------------------------
(3x-60) and y are supplementary angles .
( 3x - 60 ) + y = 180
from known x = 40 , we get y =120 from above expression
-----------------------------------------------------
y and z+10 are interior angles formed due to intersection of line p with parallel lines m and n
sum of interior angles = 180o
y + (z+10) = 180
rom known y = 120 , we get z = 50 from above expression
