Question

line RP and line RQ are tangent to point G at P and Q. if the measurement of angle PRG=35 degrees, find the measurement of angle PGR.​

Answer 1

55°

Explanation:

1. By theorem of specific circle, the radius is perpendicular to the tangential line
2. Summation of all internal angles equal to 180°

Thus from the atrachment, the angle PGR is 180°-35°-90°

= 55°
