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:
The result in standard form is: 
Step-by-step explanation:
Dividing the values:
To find the real part, we divide 2.645 by 1.15. So
2.645/1.15 = 2.3
Finding the power:
Its a division, so we keep the base, and subtract the exponents. So
Result in standard form:
The result in standard form is:
I just took the 16 chairs and added 2 since thats how many are left over, then since adding these 16 chairs, you are creating 2 more rows, so (16+2)/2 =9 Therefore, each row must have nine chairs in it and Hue starts off with 5x9+2= 47 chairs
Opposite angles formed by two intersecting lines are equal, so angle 1 is the same as angle 4. That means angle 1 = angle 5 as well.
<span>When a line intersects two parallel lines, the corresponding angles are equal. That is, if r and s are parallel, then the angles formed when l intersects r are the same s the angles formed when l intersects s. Angle 1 = Angle 5, Angle 2 = Angle 6, and so forth. Since we know angle 1 = angle 5, so from that you can see that r and s are parallel</span>
