Which equation can you use to find the value of x?
3xº
(x - 2)°

answer : 3x=78+x-2

Step-by-step explanation:

The complete question in the attached figure

we know that

The Triangle Exterior Angle Theorem states that: An exterior angle of a triangle is equal to the sum of the opposite interior angles.

In this problem

solve for x

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.
