Question

1)In the figure ,<3=61 degrees, L|| m and n is transversal find the following
a) <1=
b)<2=

Answer 1

Answer:

(a) <1= 61°

(b)<2= 119°

Step-by-step explanation:

<1=<3=61° (vertical angle)

on line m the angle with<2 which is in (linear-pair) let be x°.

so, <x = <1= 61° (corresponding angles)

Now, <x +<2 =180° ( linear - pair)

or, <2=180-<x =180°-61° =119°
