Find the area of each triangle:
1) side1 = 8 cm; side2 = 6 cm; angle = 80°
2) side1 = 10 m; side2 = 15 m; angle = 125°
3) side1 = 2.5 cm; side2 = 3.9 cm; angle = 34°
4) side1 = 4 cm; side2 = 7 cm; angle = 96°
5) side1 = 20 cm; side2 = 12 cm; angle1 = 80°; angle2 = 40°
6) side1 = 14 cm; side2 = 18 cm; angle1 = 78°; angle2 = 60°
7) side1 = 12 cm; side2 = 8 cm; angle1 = 30°; angle2 = 67°
