The value of θ from the given equation is 48.59degrees
<h3>Trigonometry identity</h3>
Given the trigonometry function
Sin(θ)=3/4
We are to find the value of theta that will make the expression true
Take the arcsin of both sides
arcsin Sin(θ)= arcsin(3/4)
θ = arcsin(3/4)
θ = 48.59
Hence the value of θ from the given equation is θ = 48.59 defense

The slope of a line perpendicular to the line y=1, would be y=-1.
Answer:
Step-by-step explanation:
The given triangle ABC is an obtuse triangle because one of its angles it greater than 90 degrees. The sum of the angles in a triangle is 180 degrees. This means that
Angle A + Angle B + Angle C = 180 degrees
Looking at the triangle,
Angle A = 30 degrees
Angle C = 20 degrees
Therefore,
30 + angle B + 20 = 180
Angle B + 50 = 180
Subtracting 50 from the left hand side and the right hand side of the equation, it becomes
Angle B + 50 - 50 = 180 - 50
Angle B = 130 degrees
