Question

2. In PQR, measure of angleP = 80º and
angle Q = 65°. Find the measure of the
exterior angle at vertex R.​

Answer 1

Answer:

angle R=145°

Step-by-step explanation:

exterior angle=P°+Q°

=80°+65°

=145°

Answer 2

Interior angle on vertex r =180°- 80°+65° (angle sum.property)

so, interior angle r = 35°

Exterior angle on vertex r = 360°(complete angle)-35° =325°

Hence, exterior angle on vertex R= 325°
