The triangle that has 35° and 25° adds up to 180 so that missing angle in that triangle is 120°.
In the line that has 120°, the missing angle adjacent is 60°.
Now, you have 60° and 60° in the triangle that has a the missing angle.
180 - (60 +60) = 60

Answer:
D
Step-by-step explanation:
The first equation of System 2 is the first equation of System 1.
The second equation has an x-coefficient of (A-L). The coefficients of x in System 1 are A and L, so (A-L) is their difference. The second equation of System 2 is the difference of the equations in System 1.
__
This is described by Choice D:
The second equation in System 2 is the difference of the equations in System 1. The first equation in System 2 is the first equation in System 1.
