Question

Supplement angle of 20 +y

Answer 1

Step-by-step explanation:

supplimentary angle of 20 +y =180 - (20+y ) = 160 -y

Answer 2

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

˚

.
