Find the measurement of angle NOP

Answers

Answer 1

Answer: to find the measure of angle NOP you must solve for x. to find x you can use the triangle angle sum theorem which states that all angles in a triangle sum to 180 degrees. Using this you can set up the equation, 180= 82 + 10x + 4x, then solve using algebra. 98=14x. 98 divided by 14 equals 7 which equals x. However, this is not the answer because angle NOP equals 4x so 7 multiplied by 4 equals 28

What is the distance between the points (-4,6) (12,-9)

Answers

Using the distance formula, we can find the distance between these two points.

$\sqrt{(x.2 - x.1)^(2) + (y.2 - y.1)^(2)}$

√(12 + 4)^2 + (-9 - 6)^2

√16^2 + (-15)^2

√481 (this is your answer.)

Luca shows his work in finding the solution to 2 - 6x = 5 - 5(x - 1) . After checking his answer in the original equation, he found that it didn't work. where did he make a mistake?

Answers

The value of x from the given equation is -8. Luca did mistake while multiplying 5 inside the terms of a bracket.

The given equation is 2-6x=5-5(x-1).

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved as follows:

Using distributive property multiply 5 to the terms in a bracket.

That is, 2-6x=5-5x+5

⇒ 2-6x=10-5x

Add 5x to both the sides of an equation

That is, 2-6x+5x=10-5x+5x

⇒ 2-x = 10

Subtract 2 to both the sides of an equation

That is, -x=8

Multiply -1 to to both the sides of an equation

So, x=-8

The value of x from the given equation is -8. Luca did mistake while multiplying 5 inside the terms of a bracket.
