Step-by-step explanation:
- 1.25 × 10^-4
- 2.0 × 10^-4
- 3.25×10^-6
Answer:
Polygons can be separated into triangles by drawing all the diagonals that can be drawn from one single vertex. If you look back at the formula, you'll see that n – 2 gives the number of triangles in the polygon, and that number is multiplied by 180, the sum of the measures of all the interior angles in a triangle.
Answer:
B. 24 units
B. (-2 , -1)
D . A(-5, 3), B(-2 , 3), C(3, -3), D(-7, 3)
Step-by-step explanation:
AC = 8, AB = 6
BC = √(8^2 + 6^2)
BC = √100
BC = 10
Perimeter = 10 + 8 + 6 = 24 units
-----------------
Area of triangle = 1/2 bh
4 = 1/2 (4) h
4 = 2 h
h = 2
remaining vertex (-2, -1)

Coordinate points of trapezoid
D . A(-5, 3), B(-2 , 3), C(3, -3), D(-7, 3)
Answer:
D. 48 in.^2
Step-by-step explanation:
Sides DE and AB are corresponding, and the triangles are similar.
linear scale factor = k = AB/DE = 12/60 = 1/5
area square factor = k^2 = (1/5)^2 = 1/25
area of ABC = area of DEF * area scale factor = 1200 sq in * 1/25
area of ABC = 48 sq in
Answer: D. 48 in.^2
