Answer:

m<3=65 degrees

Step-by-step explanation:

Since the exterior angle theorem is says:

The measure of an exterior angle of a triangle is the sum of two remote angles in a triangle so,

43+22= m<3

So m<3= 65

65°

Step-by-step explanation:

the 2 separate angles when added together will equal the 3 exterior angle because the 3 angles of the triangle should equal 180 and the horizontal line is also equal to 180. therefore 43 plus 22 is equal to 65
