Question

please answer the questions

Answer 1

angle SOT = angle POQ ...(vertically opposite angles)
angle POQ = 55°
mPR= Angle POR ..... Central America
mPR= POQ+ QOR
mPR= 55°+ 100°
MPR= 155°
mQRT is a semi arc
QOR+ROS+SOT=180°
155°+ROS=180°
ROS=180°-155°
ROS=25°......1
mRS=25°....2
mPQ=55°......3....(Central angle )
mPRT=mPQ+mQR+mRS+mST
55°+100°+25°+55°
235°
therefore, mPRT = 235 °
Hope this helps you:-))))
