1. Adjacent angles have <em>a common side + vertex</em>.
2. Vertical angles are opposite sides of each other, and have <em>two common sides and one vertex</em>.
So,
13. Adjacent: they share a side + vertex.
14. Vertical: they are opposite to each other with the same two lines.
15. Neither: they do not share any sides or vertex.
16. Adjacent: they share a side + vertex.
L=W+7
W=1/3L
we can substitute the width in the first relation with 1/3L
L=1/3L+7
we move1/3L to the left
L-1/3L=7
we multiply by 3 to remove the denominator
3L-L-21
2L=21
L=21/2=10.5cm
Answer:
x=-1 or x=3
Step-by-step explanation:
This is a quadratic equation
You can use the graph tool to visualize the x-intercepts on the graph as attached below.
x=-1 or x=3
Well,
A cylinder is actually a special type of prism. A prism is a 3-D figure made by taking a simple closed plane curve and translating it across space in a certain direction and for a given distance and then connecting the preimage and the image. A cylinder is just a prism made with a circle.
We know from translations that the image is congruent to the preimage. Thus, the bases of a (circular) cylinder are two congruent circles.
