Question

11. What is the value of x in the figure at the right? (Examples 3 and 4)

Answer 1

Answer:

x = 11

Step-by-step explanation:

• Vertically opposite angles are equal
• Angles around a point add up to 360°

Therefore, $15x + 15x + 15 + 15 = 360$

$\implies 30x+30=360$

$\implies 30x=330$

$\implies x=11$
