To find the total area of this polygon, you would have to find the areas of the rectangle and two triangles and add them up.
Area of Triangle = 1/2 x base x height
= 1/2 x 16 x 6
= 8 x 6
= 48
And since there are two triangles, we can multiply 48 by 2 to get the areas of both triangles.
Area of Both Triangles = 48 x 2 = 96
Area of Rectangle = base x height
= 16 x 10 = 160
Total Area = 96 + 160 = 256 cm2
Answer:
x = 18
Step-by-step explanation:
By the rule of Consecutive Interior Angles which define what these angles are, they both will add up to 180. As such we can put the sum of these two angles set equal to 180, and solve algebraically
(8x - 20) + (3x + 2) = 180
8x - 20 + 3x + 2 = 180
11x - 18 = 180
<u> + 18 +18</u>
11x = 198
x = 198/11
x = 18
910,000
the ten thousand place is the number 5 times to the right of the decimal
you round the 0 up or down depending on the number to the right of it, in this case, that number to the right is 5, so round up
Answer:
c = 20 (if rounded)
Step-by-step explanation:
a = 15 b = 13
225 + 169 = c^{2}[/tex]
394 =
c = 19.849433241279208
