Answer:

CAB = 70°

YZW = 120°

Step-by-step explanation:

CBA = 90° (right angle in a semicircle)

CAB = 180° - CBA - ACB ( angle in a triangle is 180°)

CAB = 180° - 90° - 20°

= 70°

YZW + YXW = 180° (opposite angle are supplementary in a cyclic quadrilateral)

YZW = 180° - YXW

= 180° - 60°

= 120°

(Correct me if i am wrong)

510 / (3000 * 4) =
510 / 12,000 =
0.0425 .....multiply by 100 to get the percent
