Y + yx; use x = 15, and y = 8

128

Step-by-step explanation:

y+yx

When x=15, y=8

8+(15×8)

=8+120=128

128

Step-by-step explanation:

from the quetsion, given that

y + yx = ?

given that x = 15

y = 8

all we need to do is to substitute for the values of x and y in the question and evaluate.

y + yx =

= 8 + 8 x 15

= 8 + 120

= 128

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.
