Write an algebraic expression for the quantities being compared.The first angle of a triangle is triple the third angle. The second angle of a triangle is 39 degrees less than the third angle.

Question

A. first angle = 3x + 39
second angle = x - 39
third angle = x
B. first angle = 3x
second angle = x - 39
third angle = x
C. first angle = x
second angle = x - 39
third angle = 3x
D. first angle = x - 39
second angle = 3x
third angle = x
