Answer:

115°

Step-by-step explanation:

The sum of angle measures of a pentagon is 540°, so your unknown angle can be found from ...

... 103° + 100° +110° +112° +unknown = 540°

... unknown = 540° -425° = 115° . . . . . . . . subtract 425° from both sides

<em>Angles of a polygon</em>

The external angles lf a convex polygon always sum to 360°. The sum of internal and external angles is, of course, 180°. So, an n-sided polygon has internal angle measures that sum to ...

... n×180° - 360° = 180°×(n -2)

Thus, a pentagon has internal angles that sum to ...

... 180°×(5 - 2) = 540°

Answer:

a = 150

Step-by-step explanation:

The sum of the internal angles of an octagon is 1080°.

$4a+4(120)=1080$ (There are four $120^{\circ}$ and 4 $a^{\circ}$ , they sum to 1080°)

$4a + 480 = 1080$

$4a = 600$

$a = 150$

One of the roots of the equation x^2-13x+q=0 is 12. Find the other root in the value of the coefficient Q.

fenix001 [56]

Considering that 12 is a root of the function, the value of coefficient Q is of 12.

<h3>What does it means that x is a root of a function f(x)?</h3>

It means that f(x) = 0.

In this problem, the function is given by:

f(x) = x² - 13x + q.

Since 12 is a root, we have that f(12) = 0, hence:

12² - 13 x 12 + q = 0

q - 12 = 0.

q = 12.

Answer:

AA similarity. The angles in both are the same.

Edit: I don't know if you need this, but a major accomplishment of King Tut and Ramses was that they encouraged the following of ancient religious beliefs among the Egyptian people .

Hope that this helps!
