Question

In Quadrilateral PQRS,RO and SO are the angle bisector of angle R and angle S respectively and meet at O . if angle P =70°and angle Q=80°,find angle ROS.​

Answer 1

Step-by-step explanation:

anglep +angleq+ angle rs=360

70+80+anglers=360

anglers=360-150

anglers=210

1/2rs+1/2s=1/2*210=105

angleors+ angleosr=180

180-105

75degree

Answer 2

Answer:

angles ROS is 75 degree

Step-by-step explanation:

50°+55°+Ros=180°

ROS = 75°
