Based on the diagram, which statement is true? A The measure of an exterior angle of a triangle, angle C, is equal to the sum of the measures of the two non-adjacent interior angles of the triangle, angle A and angle B. B The sum of the measures of the interior and exterior angles of a triangle is always 180°. C The measure of an exterior angle of a triangle, angle C, is less than the sum of the measures of the two non-adjacent interior angles of the triangle, angle A and angle B. D The sum of the measures of the interior and exterior angles of a triangle is always 360°.

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.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
