Help please! I really need it! please dont guess if you dont know, dont answer.( this is basic geometry im just dum'b) part 4

m<2 = 120

Step-by-step explanation:

When two lines are parallel and are intersected by a transversal, same side exterior angles are supplementary, meaning that their angle measures add up to 180 degrees.

Using this, one can form the equation;

m<8 + m<2 = 180

Substitute,

60 + m<2 = 180

Inverse operations,

60 + m<2 = 180

-60              -60

m<2 = 120

Step-by-step explanation:

Solution

<8 = 60 degrees.

<6 is <8s supplement

<6 + <6 = 180

60 + <6 = 180

<6 = 180 - 60

<6 = 120

<2 and <6 are corresponding angles and are therefore equal.

<2 = 120
