Question

If ABC is a triangle in which AB = 6√3cm AC=12cm , BC=6 cm,then find angle A and angle B

Answer 1

Answer:

90°

Step-by-step explanation:

AB = 6$\sqrt{3}$

AC = 12

BC = 6

$AC^{2} = AB^{2} + BC^{2}$

$(12)^{2} = (6\sqrt{3}) ^{2} + (6)^{2}$

144 = 144

Hence, it is right angled triangle.

∠B = 90°
