Consider a ∆ABC, as shown in the figure below. To prove the above property of triangles, draw a line PQ←→ parallel to the side BC of the given triangle.

∠ACB + ∠BAC + ∠CBA= 180°

Thus, the sum of the interior angles of a triangle is 180°.

But I want it in exponents and powers chapter

Yogita Ingle 5 years ago

We know that the number written as sum of the place-values of its digits is called the expanded form of a number.

Standard Form

 

Expanded Form

20,37,81,405

=

20,00,00,000 + 0 + 30,00,000 + 7,00,000 + 80,000 + 1,000 + 400 + 0 + 5

In expanded form of a number, the number is shown according to the place values of its digits.

In 2385, the place values of the digits are given below:

<a href="https://www.math-only-math.com/images/expanded-form-of-a-number.jpg" rel="gallery[pageGallery]" title="Standard Form and Expanded Form"></a>

Hence, 2385 = 2000 + 300 + 80 + 5

Thus, 2000 + 300 + 80 + 5 is the expanded form of 2385.

2/7 of 3/4 = 2/7 × 3/4 = 3/14

3/6 of 6/8= 3/6 × 6/8 = 3/8  

3/14  3/8

3 × 8     14 × 3

24   < 42

So, 3/14 < 3/8

2/7 of 3/4 < 3/6 of 6/8
