Answer:

∠AFE=140°

Step-by-step explanation:

First you have to find x angle because it will correspond with the DFE angle and then you can find the AFE angle.

To do this, you add angles BFC and CFD. BFC is 50° and CFD is 90° (because it is a right angle). 50+90=140°. Then to find x, you subtract 140° from 180°, which is 40°. So x=40°.

Then, since you know that x corresponds with angle DFE, you subtract 40°(x/DFE angle) from 180°(straight line) and you get 140°. So, ∠AFE=140°.

:) ur welcome

Factorize 2x^4-7x^3-13x^2+63x-45 using factor theorem.
zheka24 [161]
Find the possible rational roots and use synthetic division to find the first zero.
I chose x=1 (which represents the factor "x-1")

1║2  -7  -13    63  -45
  ║     2    -5  -18    45
    2  -5  -18    45    0
(x-1) is a factor, (2x³ - 5x² - 18x + 45) is the other factor.

Use synthetic division on the decomposed polynomial to find the next zero.
I chose x = 3 (which represents the factor "x-3")

3║2  -5  -18    45 
  ║     6     3   -45   
    2   1  -15     0   

Using synthetic division, we discovered that (x-1), (x-3), & (2x² + x -15) are factors.  Take the new decomposed polynomial (2x² + x -15) and find the last two factors using any method.

Final Answer: (x-1)(x-3)(x+3)(2x-5)
