Answer:
A figure formed by 3 segments connecting 3 non-colinear points.
I believe the 4th one
an=145+an-1 and a1=20
The relationship between arc, radius, and central angle in radians is:
Θ = s/r
So just plugging in the values:
Θ = (5π/3)/7 = 5π/21 ≈ 0.748 or 0.7
The answer to this question is A. 120°
Answer:
k = -9
Step-by-step explanation:
When a number (coefficient) is next to a letter (variable) that means you multiply. To solve you would to the opposite, which is to divide.
-126 ÷ 14 = -9
So -9 is equal to k.
Hope that helps and have a great day!
