There are 4 quadrants and each quadrant is has a measure of 90° angle.
Because the direction is positive, it means that the arm is going from 1st quadrant to 2nd quadrant.
90° + 90° = 180°
Because there is an additional rotation of 25°, the arm is now in the 3rd quadrant.
180° + 25° = 205°
The measure of the angle is 205°
Step-by-step explanation:
you should only make one equation:
75 + 45x = 30 + 55x
subtract the 30 frim both sides, then subtract 45x from both sides. you are left with:
45 = 10x
Divide by 10 and get:
4.5 = x
