Step-by-step explanation:
<AOF and <COD are vertical angles.
m<AOF = m<COD = 80°
Angle Addition Postulate m<BOF - m<AOF = m<AOB
m<AOB = 135° - 80° = 55°

Words:
Suppose a square is 100%,
50%: the square is divided into two equal parts, and one of them is shaded, therefore it is 50%.
25%: the square is divided into 4 equal parts, and one of them is shaded, therefore it is 25%.
150%: there are two squares, each divided into 2 equal parts, and 3 of them is shadowed, therefore it is 150%.
Answer:

Step-by-step explanation:
→ Expand out the brackets
3x + 3 < 18
→ Minus 3 from both sides to isolate 3x
3x < 15
→ Divide both sides by 3 to isolate x
x < 5
