Answer:
It is C. Linear pairs make a 180 degree turn. Hope this helps!
Step-by-step explanation:
Answer:
D one real solution
Step-by-step explanation:
x^2 - 8x + 16 = 0
This is in the form
ax^2 +bx + c = 0
so we can use the discriminant to determine the number of solutions
b^2 -4ac
(-8)^2 -4(1)(16)
64 - 64
0
Since the discriminant is zero, there is one real solution.
It’s 8/15 decimal form it’ll be 0.53 hope this helped !
Answer:
b 129%
Step-by-step explanation:
Given that the radius of the circle is 6 cm.
The central angle is 120°
We need to determine the length of AB.
<u>Length of AB:</u>
The length of AB can be determined using the formula,

Substituting
and
in the above formula, we get;

Simplifying the values, we get;



Substituting π = 3.14, we have;


Thus, the arc length of AB is 12.56 cm
