False - following the formula to find sum of all interior angles, 180(n-2), with <em>n</em> representing the number of sides, we can see that for a hexagon there's a sum of 180(6-2)=720 degrees. Then, if we broke it into 6 congruent triangles, we can see that 720/6 = 120, which is not the sum of the interior angles of a triangle.

True. Because the you will get all the areas of those 6 congruent triangles equally and so summing up them will give you the area of the hexagon.

natta225 [31]
Let total number of questions be x.

If she answered 85% correctly, than that means she answered 15% incorrectly.

You can set up the equation 15% (0.15) of total number of questions (x) equals 6.
0.15*x = 6
x = 40

There were 40 questions on the test.

Find the area of the trapezoid to the nearest tenth.
marusya05 [52]
You have not provided a diagram, therefore, I cannot provide you with the exact solution.
However, I will try to help you with the procedures on how to get the area of trapezoid and you can apply on the diagram you have.

Now, area of trapezoid can be calculated using the following rule:
area of trapezoid = \frac{b1 + b2}{2} * h

where:
b1 is the length of the first base
b2 is the length of the second base
h is the height of the trapezoid
The bases are the two parallel sides in the trapezoid

To better illustrate this, consider the attached diagram.
We have:
b1 = 5 m
b2 = 8 m
h is the perpendicular height = 4 m
Area = \frac{5+8}{2} *4 = 26 m²

Hope this helps :)
