Question

HELP PLEASE!!!!!!!!!!!!!!!!

Answer 1

Hi!

All those angles are adjacent, so they equal 180 degrees.

90+33+x= 180 < equation

123+x= 180

Subtract 123 on both sides. 

x=57

The missing angle is 57 degrees.

Have a nice day!

Answer 2

Angles on a straight line add up to 180°
~ 90° + 33° = 123°
The missing angle must be 57°
