Answer:
In naming a ray, we always begin with the letter of the endpoint (where the ray starts) followed by another point on the ray in the direction it travels. Since the vertex of the angle is the endpoint of each ray and our vertex is , each of our rays must begin with . Only fails to do so.
Answer: Telescopes use lenses or mirrors to collect and focus waves from the electromagnetic spectrum, including visible light, allowing us to look at celestial objects. By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe.
Step-by-step explanation:
The angle measurement is 68 which is a right?
Answer:
-8 + 14n
Step-by-step explanation:
-2(4-4n)+6n
Distribute the -2
-8 +8n+6n
Combine like terms
-8 + 14n
<span>To solve a triangle using law of sines you must have the length of one side and the measure of the angle opposite that particular side. Then you must have one other piece of information, either one more side length or one more angle measurement. However in some cases when the information you are given is two consecutive sides, and the angle is not between the two consecutive sides, then there exists the possibility that there are two different triangles that will satisfy the given information.</span>
