Ok. because those two angles are sumplimentary, (they equal 180 degrees) we can set up an equations.
3n+n+14=180
then isolate the variable
4n+14=180
-14 -14
4n=166
then divide to undo the multiplication
4n=166

Answer:
a reflection across a horizonal line following by a 180 clockwise
Step-by-step explanation:
Answer:
x
Step-by-step explanation:
Using the trigonometric identities
1 + tan²x = sec²x and 1 - sin²x = cos²x
secx = 
Given

= 
= 
= cos²x × cos²x
=
x
