The two angle measures are equal (which is the point of an angle bisector), so you have
y + 30 = 3y - 50
30 = 2y - 50 . . . . . . . . subtract y
80 = 2y . . . . . . . . . . . . add 50
40 = y . . . . . . . . . . . . . .divide by the coefficient of y

The value of y is 40.

Which of the following statements shows the inverse property of addition?

Olin [163]

Answer:

Statements y + (-y) = 0 shows the inverse property of addition ⇒ 1st answer

Step-by-step explanation:

Let us revise some important notes

The purpose of the inverse property of addition is to get a result of zero (any number added to its opposite will equal zero)
The purpose of the inverse property of multiplication is to get a result of 1 (any number multiplied by its reciprocal will equal 1)
The additive identity is zero
The multiplicative identity is 1
The difference between the additive identity and the inverse property of addition that additive identity states that a number plus zero equals that number, and the inverse property states that the sum of a number and its additive Inverse is zero
