The answer is x=40.
you subtract 80 from 180 to get the sum of y and 60, which is 100. because y doesn’t include the 60 degrees, you subtract 60 from 100.
then, you get 40 for y. because x is a vertical angle of y, you get 40 for x as well since they’re congruent to each other.

Answer:

40°

Step-by-step explanation:

So a straight line is 180°...

(Supplementary angle) You have 80+60=140

180-140=40°

Y= 40°

Y is equal to x since it is the alternative angle

I really need help with this. Can anyone help me please?
I am Lyosha [343]

Answer:

f(x)=(x-3)(x^2+4x+8)

Step-by-step explanation:

A polynomial function is given by the form:

f(x)=a(x-p)(x-q)...

Where a is the leading coefficient, and <em>p</em> and <em>q</em> are the roots (more can be added if necessary).

Our zeros are 3 and (-2 + 2i).

And our leading coefficient <em>a </em>= 1.

Furthermore, by the Complex Root Theorem, if (-2 + 2i) is a zero, then (-2 - 2i) must also be a zero.

So, by substitution, we acquire:

f(x)=1(x-(3))(x-(-2+2i))(x-(-2-2i))

Simplify:

f(x)=(x-3)(x+2-2i)(x+2+2i)

Expand the second and third factors:

\begin{aligned} &=(x+2-2i)x+(x+2-2i)(2)+(x+2-2i)(2i)\\&= (x^2+2x-2ix)+(2x+4-4i)+(2ix+4i-4i^2)\\&=(x^2)+(2x+2x)+(-2ix+2ix)+(-4i+4i)+(4-4i^2)\\&=x^2+4x+(4+4)\\&=x^2+4x+8    \end{aligned}

Therefore, our polynomial function of least degree and the given zeros will be:

f(x)=(x-3)(x^2+4x+8)

Can someone please help me? I have no clue.
zimovet [89]

Answer:

see explanation

Step-by-step explanation:

If 2 functions are inverses then the x and y- coordinates swap, that is

(x , y ) → (y, x )

Thus

a = - 3.8 ← the x- coordinate of the inverse

b = - 2.6 ← the y- coordinate of the inverse

c = 1.7 ← the x- coordinate of the inverse

d = 4.4 ← the y- coordinate of the inverse

e = 1.0 ← the x- coordinate of the inverse
