15+0= 15

First of all, let's take a look on the question.

$\large{15 + 0 = 15}$

Here, 0 is added to 15 and the resultant is 15 only. So, we can say that 0 when added with any number gives the same number as the resultant.

So, the property is known as Identity property because 0 is added to get the identity of the same number.

The Correct Option:

$\large{ \boxed{ \red{ \bf{Option \: C}}}}$

So, let's know more...

Commutative property ➝ a + b = b + a
Associative property ➝ a + (b + c) = (a + b) + c
Distributive property ➝ a(b + c) = ab + ac

So this is the general form of these properties which is general observed in the rational numbers.

Marcus drew a line from point Y to point W in the rectangle shown below. He created two identical triangles. Classfy the triangl

telo118 [61]

When you draw a diagonal line from Y to W, you will create two congruent triangles.

Each of these triangles will have three sides of different lengths, making them scalene triangles.

In each of these triangles, there will be one 90° angle, right angle, and two acute angles (less than 90°). This would classify these triangles as right triangles based on the angles.

Both triangles are right, scalene triangles.
