There exists the same question with the figure as shown in the attachment.
The given are:
g = 40 degrees
k = 45 degrees
Ask:
angle of " l "
So this is how to solve this:
Step 1:
Since CEF is an equilateral triangle, then each has 60 degrees.
i is equal to l because they are opposite angles
Step 2:
angle l is inside CEF, then the value of angle l is 60
