Help with this question pleaseee!!

60°

Step-by-step explanation:

As we all know, the total interior angle of any triangle is 180°. First we add all the given angles, i.e. 90+30. You get 120°. Now subtract 120° from 180° and you get 60°.

x = -2

y = 848

step-by-step explanation:

plug in the numbers

(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
