Question

How are the two angles below related? Drawing not to scale. Drawing is not to scale.

Answer 1

Answer: Hello mate!

Two angles are called "supplementary angles" when their sum is equal to 180°

The given angles are 45° and 135°, and their sum is 45° + 135° = 180°

so these angles are supplementary; this means that the lines that form them are parallel between them (the lines pointing right are parallel, and the lines pointing to the corners also are parallel)

Answer 2

we know that

Two angles are supplementary if their sum is equal to $180$ degrees

in this problem we have

$Angle\ 1=45\°$

$Angle\ 2=135\°$

so

$Angle\ 1+Angle\ 2=180\°$

therefore

the answer is

The two angles are supplementary
