Without speeding up it would take 5 1/3 seconds.. not sure if it speeds up in the question?
Answer:
fully simplified answer: x^2-2x+8
Step-by-step explanation:
Vertical angles is the answer
Supplementary means they add up to 180
Adjacent means they are next to each other
Complementary means they add up to 90
So the answer is vertical
We know that
[the length of a circumference]=2*pi*r
for r= 4 units
[the length of a circumference]=2*pi*4--------------> 25.12 units
if a full circle (360°) has a length---------------------> 25.12 units
arc for an angle of 72 °---------------------------> X
X=72*25.12/360------------> 5.024 units
the answer is
<span>the length of the subtending arc for an angle of 72</span>° is 5.024 units
