Answer:
Total reduction after 2 years = rupees
Step-by-step explanation:
Current price of a machine = 45,000 rupees
Rate of depreciation (r) = 20%
Time (t) = 2 years
Price after 2 years =
rupees
Total reduction after 2 years = rupees
The answer is 4 sixths because 4 is between 3 and 5
Answer:
A) 14°
Step-by-step explanation:
If α and β are the two angles other than 90° in a right triangle, then we have the relation between α and β as, α+β=90°.
Therefore, Sin α = Sin (90° -β) =Cos β.
So, we can write the reverse as if Sin α = Cosβ, then we have α + β =90°.
It is given that, Sin (3x-27) = Cos (5x+5).
Hence, we can write (3x-27) + (5x + 5) = 90
⇒ 8x = 90+27-5 =112
⇒ x = 14°
Therefore, option A. is correct. (Answer)
