For this problem, we apply the Angle Addition Postulate. This postulate states that the sum of all the interior angles is equal to the total angle it forms. Looking at the attached figure, this means that ∠RSU = ∠RST + ∠TSU. So, to find the value of angle RSU, you just have to add the two individual interior angles:
∠RSU = 38° + 28.6° = 66.6°
∠RSU = 38° + 28.6° = 66.6°
Answer:
The correct options are 1,2 and 3.
Step by step explanation:
According to the definition of function there exist unique value of y for each value of x in the domain of the function.
If equation have more than one values of y for any value of x, then the equation is not a function.
.... (1)
... (2)
A quadratic equation have two values of x and the value of y can be any number. So a quadratic equation is not a function.
The first and second equations are quadratic equations so the equation (1) and (2) are not functions.
The third equation is
The degree of y is 2. It means for each value of x there exist two values of y.
Put x=0, then we get
More than one values of y exist for single value of x.
So the equation (3) is not a function.
The fourth equation is
Since the degree of x is 1 and degree of y is also 1, therefore it is a linear equation and for each value of x there exist a unique value of y.
Therefore the equation (4) is a function.
