Find the value of x in each quadrilateral.

1 answer:

8 0

bearing in mind that the sum of all interior angles in a polygon is

<h3>180( n - 2 ), n = number of sides in the polygon.</h3>

well, this one is a quadrilateral, it has 4 sides, so n = 4, so the total amount for all interior angles will be 180( 4-2) = 360°, that means

$\bf 57+97+131+(15+4x) = 360\implies 300+4x=360 \\\\\\ 4x = 60\implies x = \cfrac{60}{4}\implies x = 15$

To find the x intercept set y = 0

x^2 + x - 2 =0

(x+2)(x-1) = 0

x = -2 , x = 1

$\frac{2 {x}^{5} }{15} + \frac{ {x}^{4} }{4} - \frac{ {x}^{3} }{6} + c$

simplified form =

$\frac{ {x}^{3}(8 {x}^{2} + 15x - 10) }{60} + c$

Answer:

There is no short answer.

Step-by-step explanation:

To find to intervals which f(x) increases or decreases, we first need to find it's derivative.

$f(x) = sinx - cosx\\f'(x) = cosx - (-sinx) = cosx + sinx$

The function is increasing when it's value is > 0 and decreasing when it's value is < 0.

If we take a look at this graph, cosx+sinx is positive when they are both positive or when cosx is greater then sinx on the negative part.

I hope this answer helps.
