The first step to solving this is to multiply both sides of the equation by 3
8 + 10y = 9y - 12
now move the variable to the left side and change its sign
8 + 10y - 9y = -12
move the constant to the right side and change its sign
10y - 9y = -12 - 8
collect the like terms for y
y = -12 - 8 (it equals 1 when you subtract 10 from 9 which is the same is simply saying "y")
calculate the difference on the other side of the equals sign
y = -20
this means that the correct answer to your question is -20.

I would need more information since you must use trig to find the value

Answer:
i think it's A.) 5.5
Step-by-step explanation:
A right triangle has 90°
Given: 15 and 20
15 + 20 = 35
90 - 35 = 55
55 is the missing angle
Round to the nearest tenth: 55 ÷ 10 = 5.5
