Step-by-step explanation:
Exterior angle BOA = 250°
Interior angle BOA = 360°- 250° = 110°
Now,
(A) BDA = interior angle BOA / 2 = 55°( Property of circles)
(B) From the figure, we observe that AOBC is a cyclic quadrilateral (i.e. sum of opposite angles is 180°).
Therefore, BCA + BOA = 180°
BCA = 180° - 110° = 70°
Answer:
x = 6
Step-by-step explanation:
Angle RPG = (Arc RQ + Arc SC)/2 Interior Secant Theorem
124 = (197 + 9x - 3)/2 Substitution
124 = (194 + 9x)/2 Alg
124 = 97 + 4.5x Alg
27 = 4.5x Alg
x = 6 Alg
