Step-by-step explanation:
"which is the measure of angle L?"
the total angle measures of all angles on a triangle should always equal 180
72 + 36 = 108
180 - 108 = 72!
angle L is 72 degrees!
"which angle is the vertex angle?"
from my understanding, the angle opposite the base would be the vertex angle
since j and k are equal, we can only assume 36 is the vertex angle!
hope this helps! if so, pls give brainliest!
