A circle has a circumference of 450cm
anzhelika [568]

The circumference of the circle is actually the perimeter ( length of the boundary ) of the circle . And a part of the circle which lies between two distinct points on the circumference of the circle is called an arc . If the length of the arc is less than half the circumference , it is called minor arc and remaining portion which is more than half of the circle ( but natural ) is called major arc .

When these two points , which make the arc are joined separately to the centre of circle , these arms make angle at the centre . This is called the angle subtended by the arc at the centre of the circle .

There is a beautiful logical relation exists between arc length and the angle , the arc makes ( subtends ) at the centre of the circle . This relation is as under , the wholle circle subtends an angle of 360 degree at the centre . Half the circumference subtendr 360 / 2 ie 180 degree at the centre . The logical relation becomes Arc Length = Circumference × angle in degrees it ( the arc ) subtends at the centre of the circle / 360 degree . So the answer is very simple :- The Arc Length = 36 × 90 / 360 or 9 units ( may be centimetres or metres or inches , feet , yards , etc ) . Which is definitely length of the minor arc . The length of the major arc ( remaining portion of the circumstance ) is 36 - 9 = 27 units . Hence the required answer of the sum is 9 units .

Using isosceles triangle theorems solve for x and y
klio [65]
Well lets start by getting y. We already know that all angles of a triangle will equal 180 degrees.
Therefore we know that 65 + 65 + y = 180. To solve for y we just add the two 65's then subtract that from 180
y = 180-130 = 50 Therefore y = 50

Now lets solve for x. We know that since angle B is flat it is equal to 180. The unknown value of angle B = 180 - 65
Therefore that unknown value = 115

As we previously stated all angles of a triangle equal 180. We can now come up with this equation: 115 + x + x = 180
2x = 65
x = 32.5

What is the difference of the two expressions?
valkas [14]

<em>Answer is x + 12</em>

<em />

<h2>Explanation:</h2>

Hello! Recall that you have to write clear questions in order to get exact answers. So I'll help you assuming that the two expressions are the following:

First expression:

2x+9

Second expression:

x-3

So the operation we need to perform is:

2x+9-(x-3)

Recall some rules:

(+)\times (+)=+ \\ \\ (-)\times (-)=+ \\ \\ (-)\times (+)=- \\ \\ (+)\times (-)=-

Hence:

2x+9-(x-3)=2x+9-x+3 \\ \\ \\ Combine \ like \ terms: \\ \\ (2x-x)+(9+3) \\ \\ \boxed{x+12}

What is the slope simplify your answer and write it as a proper fraction, improper fraction, or integer
worty [1.4K]

Take  2 points: (0, 70) (30, 80)

SLOPE FORMULA: y2 -y1 / x2 - x1

y2 - y1: 80 - 70 = 10

x2 - x1: 30-0 = 30

10 / 30

simplify: 1/3

This is a PROPER FRACTION
