Find the LCM of Denominators.

The LCM is 10.

Divide the LCM by the denominator of the first fraction and multiply the result by the numerator. Also do same with the second fraction. Add the results of both fractions and let the lcm be the denominator of the added results.

We have

4 + 3 /10

7/10

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.
