The present age of Joyal’s mother is three times the present age of joyal. After 5 years their ages will add up to 66. Find their present age

｡☆✼★ ━━━━━━━━━━━━━━  ☾  

Let's form some equations:

I'll refer to Joyal's age as 'x'

Therefore, his mother's age is '3x'

Here is the equation we create:

x + 5 + 3x + 5 = 66

Simplify this:

4x + 10 = 66

- 10 from both sides:

4x = 56

/4 on both sides

x = 14

3(14) = 42

So, currently Joyal is 14 and his mother is 42

Have A Nice Day ❤

(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

the answer is c hope it
