Add 4n to both sides
Subtract 3 from both sides
A = n= -2
The answer is C: Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
Explanation.
Let r = radius of the circle
Then the circumference is C = 2πr.
Let the degree measure of the arc be x degrees.
In radians, the angle is (x/180)π radians
The measure of the arc is
r*(x/180)π = (x/180)*πr
= (2x/360)*πr
= (x360)*2πr
= (x/360)*C
This proves the statement for the answer because
x/360 is the degree measure divided by 360,
C is the circumference.
Answer: 4^-2
Step-by-step explanation:
the Bases stays the same the powers changes to negative -2 because you are stubtracting 6-8 which gives you negative -2.
Consider this solution:
if AB=AC, then
m(BCD)=180°-m(BCA).
In the triangle ABC m(BCA)=m(ABC)=(180-52)/2=64°.
Finally, m(BCD)=180-64=116°.
answer: D
Yes because 5^(2x) is 18/34
