is used as my last resort. I have searched on the web, looked at given help, and asked for help from an adult but I can't get the answer. I need this fast because without this answer I can't turn the assignment in, and it needs to be submitted ASAP for any credit at all, with every question answered.
I put a screenshot of this devilish problem below (to me it's a spawn of the devil, sorry I'm frustrated right now). It's ten points so please help me.

Hi there!

The correct answer is: 135°

Step-by-step explanation:

Since the shape below has 6 sides, all angles add up to 720°

1. there are two 90° angles which means you can add them together to get 180°. Then you subtract 180 from 720 to get 540°

2. there are 4 angles that is x° so you add all them all up to get 4x° = 540

3. then divide 4 on both sides to get x = 135°

The correct answer is: 135°
