use the diagram showing m || n, as well as the relationships between interior and exterior angles of δabc, to answer the questions.
the measure of abc is 60
the measure of bac is 50
the measure of acb

60
70
120

The measure of angle ABC is  60°.

The measure of angle BAC is  50°.

The measure of angle ACB is  70°.

Step-by-step explanation:

They all add up to equal 180.

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.
