Lib _ _ _ P. So u can see they form a right angled triangle. by pythagoras ,answer would be 4 .

Similarly draw a rough diagram for 2nd one u will get the answer as √495 foot ..

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
