Q. Find an angle θ coterminal to 792∘, where 0∘≤θ<360∘.Answer:
Divide by 360: To find an angle coterminal to 792∘ that is between 0∘ and 360∘, we need to subtract or add multiples of 360∘ until the angle falls within the desired range.
Subtract full rotations: First, we determine how many full rotations are in 792∘. Since each rotation is 360∘, we divide 792 by 360. 792∘÷360∘=2.2This means that 792∘ contains two full rotations (2×360∘=720∘) and a part of another rotation.
Find coterminal angle: Next, we subtract the full rotations from 792° to find the coterminal angle within the range of 0° to 360°.792°−720°=72°
Find coterminal angle: Next, we subtract the full rotations from 792∘ to find the coterminal angle within the range of 0∘ to 360∘. 792∘−720∘=72∘ The angle 72∘ is between 0∘ and 360∘, so it is the coterminal angle we are looking for.
