Question

Please help !! thank you so much!!

Answer 1

Step-by-step explanation:

we know that:

$tan(x - y) = \frac{tanx - tany}{1 + tanx \times tany}$

using this, we can see that x = 73 and y = 13

using this, tan(x-y) = tan(73-13) = tan(60)

therefore, A = 60

we know that tan(60) = √3

therefore, B = 3
