Answer:
13) 142° (intercepted arc is twice the inscribed angle)
14) 23° (inscribed angles is half of the intercepted arc)
15) Since RT is a diameter and arcRS = 46°, then arcST = 180° - 46 = 134°
16) Using the result of #13, arcRQ = 180° - 142° = 38°

Answer:
D) L = 315 cm2 ; S = 399.9 cm2
Step-by-step explanation:
Lateral area;
3 × (½)(14)(15)
315 cm²
Surface area:
315 + (½)(14)(14)sin(60)
399.8704896 cm²
3.That BC are congruent and that AB and AC are congruent as well
