Coin Calculation plz help

I do not agree with either of them.

2^28 is the number 2 multiplied 28 times.

2^28 = 268,435,456

Step-by-step explanation:

Since exponents are repeated multiplication, you would have to multiply "2" 28 times.

Like this, 2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2.

The product of 2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2⋅2 is 268,435,456.

Therefore, I do not agree with either of them.

the answer is 8

step-by-step explanation:

3.14 x 8x8

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
