Answer:
A triangular prism
Step-by-step explanation:
The 3 rectangles represent 3 sides of the prism. Imagine folding on the line, and connecting the left side of the first rectangle to the right side of the third rectangle. It will make a triangle that has depth.
Looking that the top and bottom triangles attached to the third rectangle shows us that the top and bottom of this shape are triangles, which matches the three sides.
What we have is a 3D triangle, which we call a triangular prism
Answer:
<em>37.3° </em>
Step-by-step explanation:
sin β = 
⇒ β = arcsin = <em>37.3°</em>
Answer:
The area of this shape equals 
Step-by-step explanation:
From the diagram, we can see that this shape is a parallelogram (since opposite sides are equal to each other). The formula for the area of the parallerlogram is as follows:
(where "b" is the base, and "h" is the height).
And so we get...
Step-by-step explanation:
2 × (First Angle + Second Angle) = 360°
5x + 9x + 26 = 360°/2
14x + 26 = 180°
14x = 180 - 26
14x = 154
x = 154/14
x = 11°
The answer is B.
