Question

find the measures of text agree why degree and Z degree in the figure below where l is parallel to QR line
​

Answer 1

Answer:

x +65+60 = 180 ( linear pair property)

x = 180- 125

x= 55 degrees

z = 55 degree ( AIA )

y+ x + z = 180 ( angle sum property )

y+ 55 + 55 = 180

y = 180 - 110

y = 70

now to prove how L is || to QRas z = 55 is formed when angles are forming ALTERNATE INTERIOR ANGLES so the lines on which these angle lies are always //
