I think it’s D because if you divide 25/20 you get 1.25 and the similar pair would be 15/12.
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
secx = , cosecx =
cotx = , tanx =
Consider the left side
secA cosecA - cotA
= × -
= -
=
= ( cancel sinA on numerator/ denominator )
=
= tanA = right side ⇒ proven
Answer:
Step-by-step explanation:
A= 1/2 bh
10.98 = 1/2b (3.6)
10.98=b/2 (3.6)
10.98=b (1.8)
10.98/1.8=b
6.1=b
No solution since the two equations do not intersect
