Given that AB, DE=BC, EF=1/2, complete the statements to show that AABC- ADEF by the SAS similarity
theorem.
Horizontal and vertical lines are
So, angles are right by definition of
perpendicular lines.
All right angles are
Therefore, ABC ADEF by the SAS similarity
theorem.

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.

2y+y=5

add 2y and y
