Explanation:

There's a quick way to answering questions like this without the need to go through the whole process of finding the terms before the  

x

3

term:

Using the  

n

C

r

button, the value of  

n

represents the expansion power of  

9

and the  

r

would be the term you want to find, so in this case, it would be  

3

.

Therefore, the coefficient of the general  

x

3

term is:

9

C

=

84

However, you can only do this if the expansion is in the format of  

(

)

n

.

Answer:

6

Step-by-step explanation:

Given a parallelogram BCHS

Opposite side of the parallelogram are equal hence;

BC = HS

Given

BC = 15, BS = 12, and SH = (3x - 3),

15 = 3x-3

3x = 15+3

3x = 18

x = 18/3

x = 6

Hence the value of x is 6

Answer:

x = 36°

Step-by-step explanation:

There are 180° on a line so 180° - 126° = 54°

54° is one of the angles and so is 90° (because it is a right angle)

Therefore, now we know that x = 180° - (54° + 90°)

54° + 90° = 144°

180° - 144° = 36°

x = 36°

Answer:

x = 36

Step-by-step explanation:

solution:

we have given,

            in the right angled triangle.

             exterior angle = [tex]126^{o}[/tex]

we know,

          exterior angle = sum of interior non adjacent angle

   so,   [tex]126^o[/tex] = [tex]x + 90^o[/tex]    [∵ one angle of right angled triangle is [tex]90^o[/tex]]

     or,  [tex]x = 126^o - 90^o\\[/tex]

     or,  [tex]x = 36^o[/tex]

hence, the value of x is [tex]36^o[/tex]

Answer:

Step-by-step explanation:

you have a rectangle and a triangle,

Arectangle=8.5*8=68 cm^2

we have also a right triangle

Atriangle= 1/2 *b*h=1/2*8*9=36

Total area=68+36=104 cm^2

Answer:

21. Vol. = L ^ 3

or, 27000 = L ^ 3

or, cube root undefr 27000 = L

Therefore, Edge length = 30 cm

22.

a. v = l ^ 3

or, 64000 = l ^ 3

or, cube root under 64000 = L

or, l = 40 cm

Also,

surface area = 6 a ^ 2

= 6 * 40 ^ 2

= 6 * 1600

= 9600 cm ^ 2 #

Perimeter of Triangle -:

( 3.7 b + 1.7 +1.3b +1.1 + 7.1 c + 5.1 )

now solve by ur self

Answer:

This is because angles inscribed in a semicircles are 90 degrees (BCA)

The tanget of that circle is also a 90 degree angle to the diameter (ABD)

Therefore they're both 90 degrees

The measure of angle BCA must equal the measure of angle ABD should be that angle should be  inscribed in a semicircles that are 90 degrees,

In terms of geometry, an inscribed angle refer to the angle that should be created in the interior of a circle  at the time when two chords should be intersect on the circle. It can also be refer to the angle subtended at a point on the circle via two given points on the circle.

Also, angle should be  inscribed in a semicircles that are 90 degrees,
