Answer:
a)The number of sides of the polygon = 9 sides
b) The size of each exterior angle = 40°
Step-by-step explanation:
The sun of interior angles of a regular polygon is 1260°.Calculate the number of sides of the polygon and the size of each exterior angle.
a) The number of sides of the polygon
We solve using the formula
S = ( n - 2 ) × 180 °
Where S = Sum of the Interior angles = 1260°
1260° = (n - 2) × 180°
Divide both sides by 180°
1260°/180° = n - 2
7 = n - 2
n = 7 + 2
n = 9 sides
b) The size of each exterior angle
The sum of each exterior angle of a polygon = 360°
Hence, size of each exterior angle = 360°/number of sides of the polygon
= 360°/9
= 40°
The solution is where the 2 lines cross each other so it is:
(4,3) and (2,11)
Answer is B
45x20x18=16,200
350x9=3,150
16,200+3,150=19,350 Cubic ft
Stephen is currently 12, since he is three times as old as Gautham that means Gautham is 4. 4+8=12 which means Gautham will be 12 in 8 years.
Answer:
4
Step-by-step explanation:
<em>To start off, we are going to input our x value into our expression.</em>
3|-5| + 2(-5) - 1
<em>Next, we are going to find the absolute value (always positive) of -5 and multiply 2 and -5.</em>
3(5) - 10 -1
<em>Now, we will multiply 3 and 5.</em>
15 - 10 -1
<em>Finally, we are going to combine our like terms (15, -10, and -1)</em>
4
<em>So! Our final answer for this expression is </em><u><em>4</em></u><em>!</em>
Hope this Helps! :)
