Question

in the figure P. T is a tangent from PQR is the diameter of a circle if the angle RPT =50 degree find angle QRP?​

Answer 1

Step-by-step explanation:

angleRPT=50 degrees then angle PQR = 50 degrees ( Alternate interior angles)

angleQPR=90 DEGREES (angle formed in a semicircle)

ang(P)+ang(Q)+ang(R)=180 degrees

90+50+ ang (R) = 180 degrees

angle (R)= 180- 140

angle (R) = 40 degrees
