CAN SOMEONE HELP ME WITH THIS PLEASE AND THANK YOU.

Step-by-step explanation:

First, you want to convert the fractions to the same term. To do so, you multiply by the greatest common factor to get both denominators to be the same value.

If you have trouble understanding this, you might want to make a list of multiples. On one side, we would see all the multiples of three, and on the other, multiples of five.

3, 6, 9, 12, 15

5, 10, 15

Here we can see that the first multiple that the denominators share is 15. So, because 15 is three multiplied by five, you want to multiply that whole fraction by five. Do not multiply the whole number. Next, you want to do the same thing to the other fraction. Except, because the denominator is five and 15 is five times three, you will be multiplying the whole thing by three.

Next, because they have the same denominator, all you need to do is add. Because the numerator is greater than the denominator, you then need to add a whole number and subtract 15 from the numerator to get 2.

In summary:

original terms: 3 + 7

multiplied to get same denominator: 3 + 7

added terms: 10

simplified: 11

(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
