Question

Please help me!!!! Anyone pleaseeeee!!!

Answer 1

Answer:

69 degree

Step-by-step explanation:

Using cosine formula again :))

So we have

BC^2 = AB^2 + AC^2 - 2*AB*AC*cosA

BC^2 = 32^2 + 28^2 -2*28*32*cos56

BC = 28.3884 cm

So B:

AC^2 = AB^2 + BC^2 - 2*AB*BC*cosB

CosB=0.3559

B=69.14 degree
