Answer:
160°
Step-by-step explanation:
Explanation:
Supplementary angles have a sum of
180
˚
.
So, the supplement of a
20
˚
angle can be found through asking the question:
"
20
plus what gives me
180
?"
This can be written algebraically as:
20
+
x
=
180
To solve this, subtract
20
from both sides.
x
=
160
Hence, the supplement of a
20
˚
angle is a
160
˚
angle.
This can be proven again, since
20
+
160
=
180
, and supplementary angles have a sum of
180
˚
.
