Answer

The least positive angle coterminal with \( 345^\circ \) that is not equal to \( 345^\circ \) is \( 705^\circ \).

Solution

To find the least positive angle coterminal with \( \mathrm{A} = 345^\circ \) that is **not** equal to \( 345^\circ \), we use the concept of coterminal angles. **Coterminal angles** are angles that differ by multiples of \( 360^\circ \). Mathematically, they can be expressed as: \[ \theta = A + k \times 360^\circ \] where \( k \) is any integer. Given \( A = 345^\circ \), we need to find the smallest positive angle different from \( 345^\circ \): 1. **Adding 360°:** \[ 345^\circ + 360^\circ = 705^\circ \] This is a positive angle and is coterminal with \( 345^\circ \). 2. **Subtracting 360°:** \[ 345^\circ - 360^\circ = -15^\circ \] This results in a negative angle, which we discard since we are looking for the **least positive** angle. Therefore, the least positive angle coterminal with \( 345^\circ \) that is not equal to \( 345^\circ \) itself is \( 705^\circ \). **Answer:** \( 705^\circ \)

To find a coterminal angle with \( A = 345^\circ \), you can subtract \( 360^\circ \) since angles that differ by \( 360^\circ \) are coterminal. So, \( 345^\circ - 360^\circ = -15^\circ \). Now, if you want the least positive angle that is coterminal with \( 345^\circ \), simply add \( 360^\circ \) to \( -15^\circ \): \(-15^\circ + 360^\circ = 345^\circ\). However, since you want an angle not equal to the given measure, we can use the subtraction step: The least positive angle that is coterminal with \( A \) is: \[ 345^\circ - 360^\circ = -15^\circ \text{ (not positive)} \] \[ \text{Next, to find another, add 360} \] \[ -15^\circ + 360^\circ = 345^\circ \text{ (equal to given)} \] Instead, let's correctly approach finding a positive angle alternate to \( 345^\circ \): Subtracting \( 360^\circ \) until you land positive: \( 345^\circ - 360^\circ = -15^\circ \) Finally: Thus, the least positive coterminal angle \( ≈ 345 - 15 = 330^\circ\). The least positive angle coterminal with \( A = 345^\circ \) is \( 330^\circ \).
