The length of a rectangle is 30 cm and its width is \( \frac{2}{3} \) of its length. What will be the area of a square having a perimeter that is identical to the perimeter of the rectangle described here?
If cos 28° + sin 28° = k, then cos 17° is equal to:
-\(\frac{k}{\sqrt{2}}\)
\(\frac{k}{\sqrt{2}}\)
\(\sqrt{2}\)k
\( \frac{K}{2} \)
If (1 + tan α)(1 + tan 4α) = 2, α ∈ (0, \(\frac{\pi}{16}\)) then α is equal to:
\(\frac{\pi}{40}\)
\(\frac{\pi}{60}\)
\(\frac{\pi}{20}\)
\(\frac{\pi}{30}\)
