In the figure below, what is the measure of angle A ?

34°

I hope its right...

Step-by-step explanation:

[2x + 6x + 2x+10]°=180°{since sum of all the angle of a triangle is 180°}

=>[10x + 10]°=180°

=>10x=180°-10°

=>x°=170°÷10°

=>x°=17°

∴2x[i.e∠A]=2×17°

=34°

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.
