Step-by-step explanation:
Rewrite in Vertex form and use this form to find the vertex (h,k)
Answer:
74 degrees
Step-by-step explanation:
The arc degree measurement of the arc that is colored in orange is given as 254 degrees.
The remaining part is the part in green.
The green part plus the orange part should equal 360 degrees because that would make a full rotation around the circle.
.
The green arc has measurement 106 degrees.
We can find x by computing half the difference of the arcs there.
That is,
Hi there!
Here is what the rules says
+ * + = + (Plus times plus = plus)
+*- = - (Plus times minus = minus)
- * - = + (Minus times minus = Plus
- * + = - (minus times plus = minus)
You need to know the rules by heart because you will use it a lot.
So let see how it works with the problem
6 -(-7)
What does the rules say? It says
- * - = plus
So, we gonna use PLUS for the sign
6-(-7) = 6 + 7 = 13
13 is the correct answer.
I hope I helped. Please let me know if you have more questions.
