What is the reference angle for 197 degrees?
Add 360° 360 ° to −197° – 197 ° . The resulting angle of 163° 163 ° is positive and coterminal with −197° – 197 ° .
What is the reference angle of 210?
30∘
The reference angle is found by calculating the difference between θ and the x-axis. In this problem, 210 is closest to 180, so 210∘−180∘=30∘ .
What is the reference angle of 150?
30°
Looking at a graph, a 150° angle lies in quadrant II, therefore the reference angle is θ’ = 180° – 150° = 30°.
What is the reference angle of 171?
Trigonometry Examples Since the angle 171° is in the second quadrant, subtract 171° from 180° .
What angle is Coterminal to 197?
Trigonometry Examples The resulting angle of 197° 197 ° is positive and coterminal with −163° – 163 ° .
What is the reference angle of 240?
60 degrees
A 240-degree angle is between 180 and 270 degrees, so its terminal side is in QIII. Do the operation indicated for that quadrant. Subtract 180 from 240. You find that 240 – 180 = 60, so the reference angle is 60 degrees.
What is the reference angle of 200?
20 degrees
A 200-degree angle is between 180 and 270 degrees, so the terminal side is in QIII. Do the operation indicated for that quadrant. Subtract 180 degrees from the angle, which is 200 degrees. You find that 200 – 180 = 20, so the reference angle is 20 degrees.
What is the reference angle for 300?
360 – 300 = 60 degrees. The reference angle for 300 is 60 degrees.
What is the reference angle of 260?
80°
Reference angle for 260°: 80°
How do you find the reference angle of 665?
Subtract 360° 360 ° from 665° 665 ° . The resulting angle of 305° 305 ° is positive, less than 360° 360 ° , and coterminal with 665° 665 ° .
What is the reference angle for 275 degrees?
85°
Reference angle for 275°: 85°
What is the reference angle for 200?
20°
What is the Reference Angle for a 200° Angle? Between the angles 180° and 360°, we can say that 200° is close to 180° by 20°. Thus, the reference angle of 200° is 20°.
Is the reference angle of 195 a special angle?
195 has a reference angle of 15 which is not a special angle. So 195 itself is not a special angle (which would have made this problem easy). Now we have to find a way to express 195 in terms of special angles.
How to find the reference angle for a degree?
How to find the reference angle for degrees. All you have to do is follow these steps: Choose your initial angle – for example, 610°. If your angle is larger than 360° (a full angle), subtract 360°.
Which is the opposite of the sine of 195?
195 is a little more than 180 degrees. 195-180=15 degree difference, and this is in quadrant 3. Using how the Unit Circle is symmetric, the sine of 195 is the opposite of the sine of 15 degrees. Very likely, you want to relate this to a more familiar reference angle.
Which is not a special angle in trig?
Whenever the expression “exact value” is used in Trig. it is cods for “use special angles”. 195 has a reference angle of 15 which is not a special angle. So 195 itself is not a special angle (which would have made this problem easy).
