Answer: [tex]167^{0}[/tex]
Step-by-step explanation:
Two angles are said to be supplementary if they add up to be [tex]180^{0}[/tex]. If the first angle is x and the second angle is y , then :
x + y = [tex]180^{0}[/tex] , together the angle will form a straight line.
From the question , the first angle is [tex]13^{0}[/tex] , if the second angle is x, then
x + 13 = 180
x = 180 - 13
x = [tex]167^{0}[/tex]
