Answer:

The value of angle B is 33.69°

Step-by-step explanation:

You can find out using Tangent Rule, tanθ = oppo./adj. where opposite and adjacent are the length of triangle :

oppo. = AC = 6 units

adj. = BC = 9 units

θ = ∠B

tan ∠B = AC/BC

tan ∠B = 6/9

∠B = tan^(-1) (6/9)

= 33.69° (near. hundredth)
