x^3 + x^2 - 17x + 15 =x^3 - x^2 + 2x^2 - 2x - 15x + 15 =x^2(x-1) + 2x(x-1) - 15 (x-1) =(x-1)(x^2+ 2x -15) =(x-1)(x^2+5x-3x-15) =(x-1)[x(x+5) - 3(x+5)] = (x-1)(x-3)(x+5)

m2 = cm2/10000
10 cm2 = 10/10000 = 0.001 m2

Unit of weight is NEWTON There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth, moon, etc.

Let the smaller number = x
bigger number = 5x. -----(we need this.)

if 21 is added to both; 5x+21 = 2×(x+21)

5x + 21 = 2x + 42

5x - 2x = 42 - 21

3x =. 21

x = 21/3= 7

So the positive number is = 5×7 = 35

In figure,
transversal AD intersects two lines
PQ and RS at point B and C respectively.
Ray BE is the bisector of {tex}\angle BACQ{/tex}
So, {tex}\angle \mathrm{ABE}=\angle \mathrm{EBQ}=\frac{1}{2}(\angle \mathrm{ABQ}){/tex}
and ray CG is the bisector of {tex}\angle \mathrm{BCS}{/tex};
and {tex}B E \| C G{/tex}
We have to prove {tex}\mathrm{PQ} \| \mathrm{RS}{/tex}
Since {tex}\mathrm{BE} \| \mathrm{ CG}{/tex}
& line AD is a transversal
{tex}\angle \mathrm{ABE}=\angle \mathrm{BCG}{/tex} (Corresponding angles are equal)
{tex}\frac{1}{2}(\angle \mathrm{ABQ})=\frac{1}{2}(\angle \mathrm{BCS}){/tex}
{tex}\angle \mathrm{ABQ}=\angle \mathrm{BCS}{/tex}
But, these angles are the corresponding angles formed by transversal AD with PQ and RS

Supplement means 180° Complement means 90°

Shruti Pandey 5 years ago

Supplement is 180 Complement is 90

Kunal Thakur 5 years ago

Complement angle is 90°. Supplement angle is180°

Yogita Ingle 5 years ago

Complementary Angles:

Two angles are called complementary angles, if their sum is one right angle i.e. 90°.

Each angle is called the complement of the other. 

Example, 20° and 70° are complementary angles, because 20° + 70° = 90°.

Clearly, 20° is the complement of 70° and 70° is the complement of 20°.

Supplementary Angles:

Two angles are called supplementary angles, if their sum is two right angles i.e. 180°.

Each angle is called the supplement of the other. 

Example, 30° and 150° are supplementary angles, because 30° + 150° = 180°.

Clearly, 30° is the supplement of 150° and 150° is the supplement of 30°.
