Answer: $629.031 \text{ square centimeters}$

Step-by-step explanation:

Given : The cover of a photo album has an area of 97.5 square inches.

It is given that 1 cm = 0.3937 inches

By unitary method , 1 inch= $\dfrac{1}{0.3937}=2.54000508001\approx2.54 \text{ cm}$

Then, 97.5 square inches = $97.5\times2.54\times2.54$

$\\\\=629.031\approx629.031 \text{ square centimeters}$

Hence, The required answer is $629.031 \text{ square centimeters}$ .

38.38575 cm squared since if you multiply 97.5 * 0.3937, you get 38.38575

If sin42 degrees = 2/3 then cos48 degrees = what? If tan20.5= 3/8, the tan69.5= what?

Anna11 [10]

Big ifs, question writers. These are of course approximations.

The "co" in cosine comes from complementary angles. It means since

$42^\circ + 48 ^\circ = 90^\circ$

$\sin 42^\circ = \cos 48^\circ$

Answer: cos 48° = 2/3

Similarly,

$20.5^\circ +69.5^\circ = 90^\circ$

$\tan 69.5^\circ = \cot 20.5^\circ = \dfrac{1}{\tan 20.5^\circ} = \dfrac 8 3$

Answer: tan 69.5° = 8/3
