-12 + 2t = - 14
Solve for t

-1

Step-by-step explanation:

-12 + 2t = -14

12 + -12 + 2t = -14 + 12

2t = -2

2t/2 = -2/2

t = -1

-12 + 2t = -14

+12 +12 Add 12 to both sides as to get the 2t alone

2t = 2 Divide both sides by 2

-- --

2 2

This would leave us with t=1

(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

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
