QUESTION 8 An arc of a curve is defined by the parametric equations:
x=2(3coso - cos30), y= 2(3sino - sin30)
between the points corresponding to 0 = 0 and 0 = .
If the area, Sof the surface of revolution formed when this arc
is rotated through an angle of 2 n is in the form:
S=mi" where mand n are integers to be found.
There values of m and n are:​

i can try and you the very best that i can.

astronomers is your final answer! : )

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
