What is the answer plz help?!

We have to solve these term so that they won't have powers anymore.

First, we have to look at the powers on both numbers. 3 has a 4 and 2 has a 2.

The small numbers on the right hand corner are called powers. When those are on any term, you have to multiply the term by itself x amount of times. Since 3 has a 4 on it, we multiply the number by itself 4 times.

Our first number is 81.

And our second number is 4! Put those numbers back into their original form and you get your final answer.

(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
