Question

In the adjoining diagram, lines AB, CD and EF are parallel. Calculate the values of x and y. Hence, find the reflex angle ECA.

Answer 1

Step by Step explanation:

AB is Parallel to CD so

x+140'=180'      ( because Co-interior angles)

x=180'-140'

x=40'

similarly

EF is Parallel to CD so

y+120'=180'      ( because Co-interior angles)

y=180'-120'

y=60'

Therefor x=40' and y=60'

Note that ' the symbol above 180, 140, 40, 60 and 120 is used in place of degree symbol.
