1) Angle PRQ measures 45°.


2) Angle PQR measures 85°.


3) Angle PQR measures 40°.


4) Angle PRQ measures 50°.

Respuesta :

The sum of the interior angle of the triangle PQR is 180 degrees

Find the diagram to the question attached. From the figure, we can see that;

<PQR = 35 degrees  (alternate interior angle)

<PRQ = 75 degrees   (alternate interior angle)

Check if the sum of the angle in the triangle PQR is 180 degrees.

From the diagram, <PQR+<PRQ+<QPR = 180

<PQR+<PRQ+<QPR = 35 + 75 + 70

<PQR+<PRQ+<QPR = 110 +70

<PQR+<PRQ+<QPR = 180 degrees

Hence the sum of the interior angle of the triangle PQR is 180 degrees
