Answer:
8.2 units
Step-by-step explanation:
Given that the only information for our triangle are 2 sides and 1 angle, we must use the Law of Cosines to find side BC
<u />
<u>Recall the Law of Cosines</u>
<u />
<u>Identify angles and sides</u>
<u />
<u>Solve for side "a"</u>
<u />
Therefore, the length of line segment BC is about 8.2 units
The vertex is in the form (x, y).
The x value of the vertex is found using x = -b/2a.
After finding the x values, plug it into the given inequality to find the y value of the vertex.
Then express the vertex as a point in the form (x, y).
2/3 of an hour is 40 minutez, therefore that times 4 equals to 160 minutes or 2h and 40 minutes. The answer should be 2-3
Answer:
105
Step-by-step explanation:
180-75=105
Answer:
We know that the Pythagorean Theorem is a² + b² = c². First lets start with 6, 8, and 10. There is a simple way to know that these are Pythagorean triples. They make up what is called a 3-4-5 triangle. 3 x 2 is 6, 4 x 2 is 8, and 5 x 2 is 10. Next 5, 12, and 13 are Pythagorean triplets because 5² + 12² = 13². Because both of these form right triangles, we know that they are Pythagorean triplets.
