Solve for Y. Having trouble understanding it. Please help.

y = 4.8

Step-by-step explanation:

I set up a proportion to solve this. I divided 9.6 by 8 to find the ratio. Then, with the ratio as 1.2, I multiplied 1.2 and 4 together to get 4.8, which is y.

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.
