Powers 215 - 8 * 4 + 15 * 6 =

2) 100 : 10 + 82 * 5 - 407 =

3) 92 : 2 - 4 * 5 - 8 * 3 =

¿can someone help me?

1 answer is 93,2nd answer is 13 and 3rd answer is 2.

answer:  

123455421

step-by-step explanation: easy

(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
