Elanso [62]3 years ago
6 0

Answer:

Check the proof below

Step-by-step explanation:

try to verify from RHS to LHS

(Tan a + tan b) / (tan a - tan b)

= (sin a / cos a + sin b /cos b) / ( sin a/ cos a - sin b/ cos b)

= (sin a cos b + cos a sin b)/ (sin a cos b - cos a sin b)

= sin (a+b) / sin (a-b)

Fyi

sin(A+B) = sinAcosB+cosAsinB

sin(A-B) = sinAcosB-cosAsinB

A is (-2,-5) A’is a glide relection where the translation is (x,y) Is(x+7,y) the line of reflection is y=2 What are the coordina
erma4kov [3.2K]

Answer: A' (5,9)


Step-by-step explanation:

1. You have that the translation is (x,y)⇒(x+7,y) and the coordinates of A is (-2,5). Then:

A(-2+7,-5)⇒A(5,-5)

2. As you can see, -5 is 7 units below of the line of reflection y=2, therefore, you can know the coordinates of A' as following:

A'(5,7+2)\\A'(5,9)

3. Then, the coordinates of A' is (5,9)
