Question

In A ABC, AB= 6√3cm
find angle B
A C = 12cm and BC = 6cm​

Answer 1

Answer:

90°

Step-by-step explanation:

it can be seen in the question that-

12^2= 6√3^2 + 6^2

144= 108+36

AC^2 = AB^2 + BC^2

Answer 2

Answer:

Given, AB = 6√3 cm

BC = 6 cm

AC = 12 cm

We can clearly see that it satisfies pythagoras theorem which means ∆ABC is a right angled triangle

Angle B is 90° because AC is hypotenuse and AB is perpendicular to BC
