Answer:
x = 111
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 7, thus
sum = 180° × 5 = 900°
Sum the given interior angles and equate to 900
x + 139 + 121 + 125 + 126 + 158 + 120 = 900, that is
x + 789 = 900 ( subtract 789 from both sides )
x = 111
Answer:
D
Step-by-step explanation:
A is origin, B is 2nd quad, and C is 4th quad
Tan(33) = 0.6494
This is just a problem for your calculator. Most put the number in as
Tan(
3
3
=
You just find the area of the triangle, and do that times 4 that number. The formula for finding the area of a triangle is half the base times the height 3 * 9 = 27. So the area of the triangle is 27 and the area of all 4 of the triangles would just be 27 * 4 = 108. Now for the square. Formula for finding the area of a square is length times width which would be 6 * 6 = 36. So then you do 36 + 108 = 144
So the area of the net is 144M
