Is the measure of two exterior angles of a triangle PQR, each equal to

OA:D
First simplify the question:Is the measure of two exterior angles of a triangle PQR, each equal to 120 degrees?
For a given triangle, Sum of all exterior angle is \(360^{\circ}\).

if two exterior angles of a triangle PQR are to be 120 degrees i.e total \(2*120^{\circ} =240^{\circ}\),Third exterior angle should be also \(360^{\circ}-240^{\circ}=120^{\circ}\)
\(\angle\)P=\(\angle\)Q=\(\angle\)R= \(180^{\circ}-120^{\circ}\)(\(120^{\circ}\) being exterior angle)
\(\angle\)P=\(\angle\)Q=\(\angle\)R=\(60^{\circ}\)
Question is reduced to whether \(\triangle\)PQR is an equilateral triangle or not?

Statement 1 : PQR is NOT an isosceles triangle.
If PQR is not even isosceles triangle , it cannot be equilateral triangle.
So Statement 1 alone is sufficient to answer whether \(\triangle\)PQR is an equilateral triangle or not?

Statement 2 :Measure of angle P is 70 degrees.
Measure of \(\angle\) P is not \(60^{\circ}\), so PQR is not an equilateral triangle.
So Statement 2 alone is sufficient to answer whether \(\triangle\)PQR is an equilateral triangle or not?

so OA should be D
