Question

it is related to chp. circle. pls answer ​

Answer 1

Answer:

(i) 50°  (ii)30°

Step-by-step explanation:

(i)∠RKS=90°   (angle in a semicircle=90°)

sum of angles in a triangle=180°

∠RSK+∠RKS+∠SRK=40°+90°+∠SRK=180°

∠SRK=180-130=50°

(ii)∠ROQ=180-80=100°

   ∠SRQ=50°

Sum of angles =180

100+50+∠PQR=180°

∠PQR=180-150=30°
