Question

8 cm B 106° 14 cm ABC is a triangle. AB = 8 cm BC= 14 cm Angle ABC= 106 Calculate the area of the triangle. Give your answer correct to 3 significant figures.​

Answer 1

53.816 cm²

Explanation:

Area of the triangle is:

[(AB)(BC)sin(ABC)]/2

= [8*14*sin(106)]/2

= 4*14*sin(106)

= 56*sin(106)

= 56*0.961

= 53.816
