Answer:

<1= 135 degrees

<4= 135 degrees

<6= 45 degrees

Step-by-step explanation:

This is because angle two and 6 are corresponding angles. you would then subtract 180 from 45 because angle 6 and 4 are consecutive angles. This would give you 135 degrees. Then angle 1 and angle 4 are verticla agles, making them equal to each other.

What property was applied to solve the equation below?
melisa1 [442]

Answer:

Division property

Step-by-step explanation:

The property which states that we can divide both side of the equation by the same non-zero number is called the division property of equality.

The goal of dividing an equation is to isolate the unknown variable on one side.

For example, let the equation be:

2×x=10

Since the unknown variable x is being multiplied by the number 2, to isolate the variable an inverse operation needs to be applied - division:

2×x÷2=10÷2

Careful! Never forget to write the same operation on both sides of the equation! When doing so, the solution of the equation stays the same, i.e. we get an equivalent equation.

How do you calculate the area of a circle?
Eduardwww [97]
<h2>Hello!</h2>

The answer is:

Area_{circle}=\pi *radius^{2}

or

Area_{circle}=\pi *(\frac{diameter}{2})^{2}

<h2>Why?</h2>

We can calculate the area of any circle using the following formula:

Area_{circle}=\pi *radius^{2}

Where,

π, is a constant used to calculate the area of the circle.

radius, is the distance from the center to any point of the circle.

Also, we have that:

radius=\frac{diameter}{2}

So, we can rewrite the equation by the following way:

Area_{circle}=\pi *(\frac{diameter}{2})^{2}

Have a nice day!
