Answer:
4. 25.0 in
5. 14.0 cm
6. 21.0 cm
Step-by-step explanation:
4. RT/sin28 = 12/sin13
RT = sin28 × 12/sin13
RT = 25.03393131
5. Angle K = 180 - 17 - 42 = 121°
41/sin121 = HK/sin17
HK = sin17 × 41/sin121
HK = 13.9847144
6. Angle y = 180 - 39 - 51 = 90°
27/sin90 = YZ/sin51
YZ = sin51 × 27
YZ = 20.98294096
