Sin³(x)cos⁴(x) = sin(x)[cos⁴(x) - cos⁶(x)]
      sin(x)                         sin(x)
sin²(x)cos⁴(x) = cos⁴(x) - cos⁶(x)
sin²(x)cos⁴(x) = cos⁴(x)[1] - cos⁴(x)[cos²(x)]
sin²(x)cos⁴(x) = cos⁴(x)[1 - cos²(x)}
     cos⁴(x)                  cos⁴(x)
           sin²(x) = 1 - cos²(x)
       + cos²(x)      + cos²(x)
                    1 = 1

olga55 [171]

Answer:

It can

Step-by-step explanation:

The sum of two lengths have to be greater than the other one in order to be a triangle. At first glance you can see 24+32 is greater than 40, 40+32 is greater than 24 and 24+40 is greater than 32.

(b) Four of the interior angles of a 12 sided polygon are each x °. The other angles are 2xº each. Calculate the value of x.​
Sergio [31]

Answer:

Step-by-step explanation:

Sum of all the angles of 12 sided polygon= (n -2)*180

   = (12 - 2 )*180 = 10 * 180 = 1800

Four interior angle each of xº +  8 interior angles each of 2xº = 1800

4*x  + 8*2x = 1800

4x + 16x = 1800

20x = 1800

x = 1800/20

x = 90°

Help me please? :))))
hram777 [196]

Answer:

(C)

Step-by-step explanation:

The least common denominator between a denominator of 10 and 4 is 20, so to make the denominators of both fractions equal to 20 you have to multiply the first fraction by 2/2 and the second fraction by 5/5.

Hope this helps :)
