Answer:
<h3><u>3/4</u></h3>
Step-by-step explanation:
1/3+5/12=3/4
The sum of the angles should be 180, so x+ (x+10) + (x+5) = 180. This simplifies to 3x + 15 = 180, so 3x = 165, so x=55.
Answer:
<h3>A cube</h3>
Step-by-step explanation:
Vertices of a solid shape is a point where 2 lines or edges of the shape intersects. If tom has a cube a rectangular prism and a triangular prism, then the cube has 8 vertices, a rectangular prism has 5 vertices (a rectangle has 4 vertices plus the point where all the lines coming from the vertices of the rectangle intersects).
Also, a triangular prism has 4 vertices(a triangle has 3 vertices plus the point where all the lines coming from the vertices of the triangle intersects)
Hence the only shape that has more than 6 vertices is a cube.
That would be, with full working out,
1w + 14w, which equals 15w, then you - 6w, which makes 9w
