Please I need help with this

Step-by-step explanation:

Can you please post the qn one by one? Cuz this so hard to answer them all.

1) Mark subsititued 5 squared and reintroduced in in the center of the equation.

2)  He needed to replace 3 squared

3) 4 squared 3 to the radical of 3 squared (5 times)

4) Yes it would  be those 5 times 3 squarred Step-by-step explanation:

hlo how are you friend

what do you mean by fog

step-by-step explanation:

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.
