Answer:

x = 19 degrees

Step-by-step explanation:

Hi there!

We're given that CD = DE. This makes angle ECD equal to 38 degrees (equal to angle CED).

The sum of the interior angles in a triangle is 180 degrees. Now, we can use this information to find angle D:

180-38-38=D

D=104

Therefore, angle D is 104 degrees.

This is a parallelogram, so angle B is also 104 degrees.

The sum of the interior angles in a quadrilateral is 360 degrees. Now, we can use this to find angle A:

360-104-104=A+C

152=A+C

Keep in mind that because this is a parallelogram, angles A and C are equal:

152=2A

A=76

Therefore, angle A is 76 degrees.

To solve for x, we can use the following equation:

3x+x=76

4x=76

x=19

Therefore, x is 19 degrees.

I hope this helps!

Create a 5th degree trinomial that has a constant term of 3.

erastovalidia [21]

Answer:

$4x^5\:+\:9x^2\:+\:3$ is a trinomial having three terms, with degree 5 and the constant term '3'.

Step-by-step explanation:

Considering the trinomial

$4x^5\:+\:9x^2\:+\:3$

As the polynomial contains 3 terms, so it is a trinomial.

As the highest power of the variable 'x' is 5, so the degree of this polynomial is 5.

Any term with no variable is called a constant term. so, 3 is a term with no variable. Therefore, the constant term is 3.

Therefore, $4x^5\:+\:9x^2\:+\:3$ is a trinomial having three terms, with degree 5 and the constant term '3'.

1) A line with gradient 2 passes through (0, 4). Write down the equation of the line.

blondinia [14]

For the attached image, note that slope is the same thing as gradient.

1) y = 2x + 4

2) Substituting in x = 1 and y = 1,

1 = 4(1) + c

1 = 4 + c

c = -3

So, the equation is y = 4x - 3
