Answer:
60
Step-by-step explanation:
15 times 5 is 75 75 minus 15 is 60 so the answer is 60
Answer:
see explanation
Step-by-step explanation:
Using the cofunction identities
tan(90 - A) = cotA and cscA = sec(90- A)
Consider the left side
tanA + tan(90 - A)
= tanA + cotA
=
+ 
= 
= 
=
× 
= secA × cscA
= secA. sec(90 - A) = right side ⇒ verified
