Answer:
146°
Step-by-step explanation:
Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circle. Given m arch AB=64° and ⦣ABC=73°, m ⦣ABC=__ ° and m arch AC=__ °.
Solution:
Given that:
arc AB = 64° and ⦣ABC=73°
The Central Angle Theorem states that the central angle from two chosen points A and B on the circle is always twice the inscribed angle from those two points. The inscribed angle is any point along the outer arc AB and the two points A and B.
Therefore arc AC is the central angle of ⦣ABC. Using the central angle theorem gives:
arc AC = 2 * ⦣ABC
substituting:
arc AC = 2 * 73
arc AC = 146°
If it is in a square formation, you would have to find the square root of 36 which is 6
Answer:
25 ft
Step-by-step explanation:
You need to add 9+7+9.
There are two 9s and just one 7. 9+9 is 18 and 18+7 is 25
Answer:
It equals 3, but if you add two negatives inside of the parenthesis, then it equals -19.
Step-by-step explanation:
You have to plug in the numbers where the variables are, so it would be -8-(-11).
