Find the area of the triangle with A = 60°, b = 11 feet, and c = 8 feet. Round to the nearest tenth.
1 answer:
Answer:
Area = 38.1 ft² (nearest tenth)
Step-by-step explanation:
Use sine rule for area of a triangle:
Area = (1/2)ab sin(C)
= (1/2)bc sin(A)
= (1/2) x 11 x 8 x sin(60)
= 22√3
= 38.1 ft² (nearest tenth)
