Answer:
Step-by-step explanation:
21. 136° and b are supplementary, meaning they have a sum of 180°. This means that 136° + b = 180° → b = 44°.
22. Again, the angles are supplementary which means that 61° + b = 180° → b = 119°.
23. Again, they are supplementary which means that x - 22° + 135° = 180° → x + 113° = 180° → x = 67°.
24. I'm pretty sure you get the gist of this. 6x + 3° + 87° = 180° → 6x + 90° = 180° → 6x = 90° → x = 15°
Hope this helps!
