16 + 40 ÷ 4 + (13 - 9)2

Step-by-step explanation:

= 16 + 40 ÷ 4 + ( 13 - 9 ) 2

= 16 + 40 ÷ 4 + 4 × 2

= 16 + 10 + 4× 2

= 16+ 10 + 8

= 34

8 apples are left.

step-by-step explanation:

10-2=8

10 apples

take 2

now u have 8

(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
