Question

129° 95° 47° 121° 47 95 85 133

Explanation:

Step1: Use linear - angle property

A linear - pair of angles sums to 180°. Angle 1 and the 129° angle are a linear pair. So, $\angle1=180 - 129=51^{\circ}$.

Step2: Use angle - sum property of a triangle

In the left - hand triangle, we know one angle is $\angle1 = 51^{\circ}$ and another is 95°. Let the third angle be $\angle2$. By the angle - sum property of a triangle ($\angle1+\angle2 + 95^{\circ}=180^{\circ}$), we have $\angle2=180-(51 + 95)=34^{\circ}$.

Step3: Use vertical - angle property

Angle 3 and the 47° angle are vertical angles, so $\angle3 = 47^{\circ}$.

Step4: Use angle - sum property of a triangle for the right - hand triangle

In the right - hand triangle, we know one angle is $\angle3 = 47^{\circ}$ and another is $\angle6$. First, find $\angle7$. Since $\angle7$ and the 121° angle are a linear pair, $\angle7=180 - 121 = 59^{\circ}$.
Let's assume we want to find an angle related to the given options. If we consider the fact that we can use the angle - sum property of a triangle in the right - hand triangle with $\angle3 = 47^{\circ}$ and $\angle7 = 59^{\circ}$, and we know that the sum of the interior angles of a triangle is 180°. Let the third angle in the right - hand triangle be $x$. Then $x=180-(47 + 59)=74^{\circ}$. But this is not in the options.
If we consider the fact that the angle adjacent to the 47° angle (let's call it $\angle4$) in the right - hand triangle's outer region. Since the 47° angle and $\angle4$ are a linear pair, $\angle4 = 180 - 47=133^{\circ}$.
