Given △jkl, sin(38°) equals

cos(38°).

cos(52°).

tan(38°).

tan(52°).

By definition, we have to:

Where,

x: angle

C.O: opposite leg

C.A: adjacent leg

h: hypotenuse

Using the definitions we have that for sin (38 °):

Then, we have the following trigonometric relationship:

Therefore, it is true that:

Sin(38) = cos(52)

Given △JKL, sin(38°) equals:

cos(52°).

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.
