PLEASE I NEED HELP WITH THESE TWO WILL GIVE BRAINLIEST Pre-Algebra

it seems so obvious i just dont know lol

1) There are 16 science problems and 26 math problems.

Step-by-step explanation:

x is the number of science problems

x+x+10=42

2x+10=42

2x=32

x=16

(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

answer: apothems is your answer

step-by-step explanation: hope u get it right
