Two angles are vertical angles. One angle is labeled 2x∘. The other angle is labeled ( x +30 ) ∘. Find the value of x.
Group of answer choices

30°

Step-by-step explanation:

Vertical angles are equal

So, 2x=x+30

2x-x=30

x=30°

step-by-step explanation:

(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
