1.	7. In APQR, PRQ 90°, RSQ 90°Find:(a) CRSP(b) ZPRS(c) ZRQS60°
Answer» angle RSP = 90°angle PRS = 30 = [180 - (90+60)]( sum of interior angles of triangle is 180) angle RQS = 30°angle PRQ = 90 ( given). But, angle PRS is 30°(just obtained above). So, angle ,SRQ = PRQ -PRS => SRQ= 90-30 = 60 now,because(sum of interior angles of triangle is 180) therefore angle RSQ = 90-60=30°

Answer»

angle RSP = 90°angle PRS = 30 = [180 - (90+60)]( sum of interior angles of triangle is 180)

angle RQS = 30°angle PRQ = 90 ( given). But, angle PRS is 30°(just obtained above). So, angle ,SRQ = PRQ -PRS => SRQ= 90-30 = 60

now,because(sum of interior angles of triangle is 180)

therefore angle RSQ = 90-60=30°
