Answer:
Step-by-step explanation:
Given : 
We have to write which identity we will use to prove the given statement.
Consider
Take left hand side of given expression 
We know
Comparing , we get, a= 180° and b = q
Substitute , we get,
Also, we know 
and 
Substitute, we get,
Simplify , we get,
Hence, use difference identity to prove the given result.
15=2y-5
move -5 to the other side
sign changes from -5 to +5
15+5= 2y-5+5
15+5= 2y
20= 2y
divide both sides by 2
20/2= 2y/2
y= 10
Answer : y= 10
Answer: 164.26, 77.08, 2405.364
