Question

in a triangle Ab=6√3, Bc=6, Ca =12, find angle B​

Answer 1

Answer:

90°

Step-by-step explanation:

AC^2= AB^2+ BC^2

12^2 = (6√3)^2 + 6^2

144= 108 + 36

144= 144

so ABC triangle is a right angled triangle ( by Pythagoras Theorem)

AC is hypotenuse and angle B = 90°

Answer 2

Answer:

the ratio of sides is 3:6:9 so, opposite angle of ca = b. So b= 90 degree . a = 30 degree c= 60 degree
