A number approximated 1.1176 to two significant figures instead of two decimal places. Find the percentage error.

Here are the solutions to the remaining questions.

Question 17: Circle properties
In the diagram, P, Q, R are points on the circle with center O. Given $\angle QPO = 77^\circ$ and reflex $\angle QOR = 220^\circ$. Find the value of $\angle QPR$.

Step 1: Find the minor angle $\angle QOR$.
The sum of angles around the center of a circle is $360^\circ$.

$$\text{Minor } \angle QOR = 360^\circ - \text{Reflex } \angle QOR$$ $$$$
