Answer:
4
Step-by-step explanation:
The number of edges connecting to that vertex is 4. (It doesn't matter that two of them both go to vertex A.)
Vertex E has degree 4.
Answer:
216°
Step-by-step explanation:
Both chords are the same length, so the left and right arcs are both 72°. The whole circle is 360°, so:
72° + 72° + x = 360°
x = 216°
Answer:
5 perpendicular and 4 parallel line segments so more perpendicular
Perpendicular means "at right angles". A line meeting another at a right angle, or 90° is said to be perpendicular to it. And Parallel Lines or parallel Segments are always the same distance apart, they will never meet. And in this shape there are four parallel line segments and five perpendicular
Probably the last one
Use the equation for the area of a triangle 1/2(bxh)
Then multiply that number by 2 to get the area of the complete shape.
