The radian measure of an angle theta is the length of the arc that subtended angle 2Pi

We can measure angle in two form degrees or Radian.

What is the meaning of radian?

Radian can be described as a measure of angle subtended by a circular arc. It can be defined as the ratio of the arc length subtending angle to the radius of circle.

One radian is the measure of angle subtended by by an arc that is equal to the radius of circle.

Therefore,the radians measure an angle theta the length of arc.

Θ =s/r ,

where, theta is the angle subtended, s is the arc length and r is the radius of circle.

We know that the 2π radians = 360 degrees.

That subtends the angle in a circle of radius 2Pi

Therefore ,The radian measure of an angle theta is the length of the arc that subtended angle 2 Pi

The key is to check whether the given side measures satisfy the triangle inequality theorem or not, if yes then we can create a unique triangle, if no then no triangle can be created, and if the given measures are the perimeter of a triangle, we can create many triangles.

When given three side measures of a triangle, the following scenarios can occur:

Unique triangle: If the three side measures given are the lengths of the three sides of a triangle and they satisfy the triangle inequality theorem, then we can create a unique triangle. The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

No triangle: If the three side measures given do not satisfy the triangle inequality theorem, then it is not possible to create a triangle with those side lengths.

Many triangles: If the three side measures given are the perimeter of a triangle, and we are allowed to vary the lengths of the three sides of the triangle within a certain range, then we can create infinitely many triangles.

Example: A triangle with perimeter 12cm, we can create a unique triangle with sides 3,4,5, or we can create many triangle with sides (2,5,5), (4,4,4),(3,4,5) and so on.

The value of x for the given angles is 23

A transversal is a line that, at two different locations in the geometry, cuts through two lines in the same plane. The angles that result from a transversal crossing of two lines in pairs can be successive internal angles, matching angles, or alternate angles.

Given lines m and n, where m ║ n

and t intersect at both the lines as shown in the figure,

so line t works s transversal,

and angles,

(8x - 27)° and (7x - 4)°

both the angles are at the bottom of the line and same side so they are corresponding angles,

and corresponding angles for any transversal are equal,

(8x - 27)° = (7x - 4)°

8x - 27 = 7x - 4

Answer:

218 with a remainder of 2

Step-by-step explanation:

656 divided by 3 = 218.6666667

218 times 3 = 654

656 - 654 = 2

When 656 is divided by 3 is 218 with a remainder of 2.

In mathematics, divides left-hand operands into right-hand operands in the division operation.

To divide 656 by 3, we can perform long division as follows:

 3 ) 656 (218

     -6

     ____

     15

    -12

   _____

      35

    - 33

    _____

       2

We first divide the first digit of 656 (which is 6) by the divisor 3, which gives us 6 with a remainder of 15.

We then bring down the next digit (which is 56) to form the dividend 18, and we perform the division again.

This gives us 218 with a remainder of 2.

Therefore, 656 divided by 3 is 218 with a remainder of 2.

To write 300000000 in standard form, we need to move the decimal point to the left or right so that there is only one non-zero digit to the left of the decimal point.

300000000 in standard form would be written as 3 x 10^8.

To arrive at this form, we move the decimal point 8 places to the left (since there are 8 zeros in 300000000) and add the power of 10 notation, indicating that we moved the decimal point 8 places to the left. The number 3 is the coefficient and 8 is the exponent. This way, we get 3 x 10^8 which is the standard form of 300000000.

Standard form, also known as scientific notation, is a way of expressing a number in a compact and efficient manner. It is typically used for very large or very small numbers.

When a number is written in standard form, the decimal point is moved so that there is only one non-zero digit to the left of the decimal point. The number of places the decimal point is moved is indicated by a power of 10.

Check the picture below.

If the two lines crossed are parallel, the alternate angles are equal. It is proven that the sum of the three angles of a triangle is equal to 180 degrees.

We have to prove that ∠A + ∠B + ∠C is equal to 180 degrees.

The measure of A = ∠1

B = ∠2

C = ∠3

Given, l || BC

We know that the alternate angles are equal in parallel lines.

∠2 = ∠4 -------------- (1)

∠3 = ∠5 -------------- (2)

Adding (1) and (2),

∠2 + ∠3 = ∠4 + ∠5

By adding ∠1 on both sides,

∠1 + ∠2 + ∠3 = ∠4 + ∠5 + ∠1

From the figure,

The sum of the angles at a point on a line is equal to 180 degrees.

∠4 + ∠1 + ∠5 = 180°

So, ∠1 + ∠2 + ∠3 = 180°

Therefore, ∠A + ∠B + ∠C = 180°

Thus, If the two lines crossed are parallel, the alternate angles are equal. It is proven that the sum of the three angles of a triangle is equal to 180 degrees.
