Here's something you should remember:
[tex]\bigstar[/tex] Complementary angles add up to 90 degrees.
[tex]\bigstar[/tex] Supplementary angles add up to 180 degrees.
Here, we have two supplementary angles. Their measures are:
133 and x.
We know that supplementary angles add up to 180 degrees, so all we have to do is solve this equation for the unknown variable, x:
x+133=180
We subtract 133 from [tex]\bold{BOTH}[/tex] sides:
x=180-133
x=47 degrees
