Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
1 + tan²A = sec²A , secA =
, cosecA =
, cotA =
, tanA = 
Consider the left side

= 
= 
= 
=
× sin²A
= 
= tanA = right side , thus proven
Answer:
h=5
Step-by-step explanation:
Because 5*3=15 so the answer is h=5 units
Check the picture below.
