Those are two vertical angles, and vertical angles are congruent,
so x+9=3x-27
2x=36
x=18
x+9=18+9=27
each angle is 27 degree

Please explain this to me.

Nutka1998 [239]

Answer:

The value of x is 12 units.

Step-by-step explanation:

We know that:

Formula: h² = a² + b²

Let's solve using Pythagoras theorem.

=> 13² = 5² + x²
=> 169 = 25 + x²
=> 169 - 25 = x²
=> 144 = x²
=> √x² = √144
=> x = √144
=> x = 12

Hence, the value of x is 12 units.

A circular plate has circumference 21.4 inches. What is the area of this plate? Use 3.14 for pi.

Brut [27]

Answer:

The area of this plate is $36.31\ \text{inches}^2$ .

Step-by-step explanation:

We have,

Circumference of a circular plate, C = 21.4 inches

The circumference of a circular shape is given by :

$C=2\pi r$

r is radius of circular shape

$r=\dfrac{C}{2\pi}\\\\r=\dfrac{21.4}{2\times 3.14}\\\\r=3.4\ \text{inches}$

Area of this plate is given by :

$A=\pi r^2\\\\A=\pi (3.4)^2\\\\A=36.31\ \text{inches}^2$

So, the area of this plate is $36.31\ \text{inches}^2$ .
