Question

in the given figure l parallel to m and t is a transversal . if ∆5 =70° . find the measure of each of the angle ​

Answer 1

Answer:

Given, L||M and t is a transversal.

angle 5=70°

angle 5=angle 1 (corresponding angles )

so,angle 1=70°

---------------------------------------------------------

angle 5=70°

angle 5=angle 3 (Alternative interior angle )

so,angle 3=70°

-----------------------------------------------------------

angle 5=70°

angle5+angle 4=180°(connsecutive interior angle )

70°+angle 4=180°

angle 4=180°-70°=110°

----------------------------------------------------------

angle 4=110°

angle 4=angle 8 (corresponding angle)

so , angle 8=110°
