It’s the first one if it’s not then my bad g
This can be expanded through the tangent angle addition formula:
tan(α+β)=tanα+tanβ1−tan -α + tanβ
Thus,tan(x+y)=tanx+tany1−tan x tany
Hope it helps you

Answer:
the answer would be 15
Step-by-step explanation:
1/3 x 1/5 =1/15
Point B is used for both triangles and is located in the same place, which means triangle ABC was rotated at point B
Then triangle ABC was reduced in size to make DBE, which is called a dilation.
The first drop down should be Rotation and then dilation.
The second drop down should be Similar.
