Question

Determine the value of a' from the figure below Also, find angle - ROS, angle - SOT and angle - TOU.​

Answer 1

Answer:

We know that:

angle POU is equal to angle ROS by V. O. A

and same for angle QOP and angle ROQ.

Now, ROS+SOT+TOU=180 degree by(angles made on a straight line)

=2a+a+3a=180

=6a=180

a=30degree

Now,

angle:

ROS=2*30=60degree

SOT=30 degree

TOU=3*30=90degree
