Step-by-step explanation:

From ABC to A'B'C'

it is a rotation 90 degrees anticlockwise about the origin i.e (0,0)

From A'B'C' to A''B''C''

It is a reflection about the x axis.

Three exterior angles of a pentagon measures 60,80and 90.Find the measure of other two exterior angle, assuming them equally Tha

julsineya [31]

Given:

The three exterior angles of a pentagon measures 60,80 and 90.

To find:

The measure of other two exterior angle, assuming them equally.

Solution:

Let x be the measure of two other exterior angles of the pentagon.

We know that the sum of all exterior angles of a pentagon is 360 degrees.

$60^\circ+80^\circ+90^\circ+x+x=360^\circ$

$230^\circ+2x=360^\circ$

$2x=360^\circ-230^\circ$

$2x=130^\circ$

Divide both sides by 2.

$\dfrac{2x}{2}=\dfrac{130^\circ}{2}$

$x=65^\circ$

Therefore, the measures of both exterior angles are 65 degrees.

Answer:

12x³ - 3x

Step-by-step explanation:

Given 

f(x) = x and g(x) = 4x² - 1

Now, 

3 f(x) * g(x) 

= 3 * x (4x² - 1)

= 3x ( 4x² - 1 )

= 12x³ - 3x 

Hope it will help :)
