• What is the exact value of Cos 135?

cos135° = cos (90+45)° 45° is the reference angle. cos 45° = sqrt (2)/2, cos135° = – sqrt (2)/2 since cos theta is negative in Quad II. *** For Quad II reference angles take 180 – x ***. I took 180 – 135 = 45. It was the rest of the angle down to 180 that I wanted NOT the c in 90 + c above.

### How would you write 135 as a fraction?

Write down the number as a fraction of one: 0.135 = 0.135 1

• Multiply both top and bottom by 10 for every number after the decimal point: As we have 3 numbers after the decimal point,we multiply both numerator and
• Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them.
• What is the exact value of Cos 135 degrees?

Using trigonometric identities, we can write sin 135° in terms of cos 135° as, sin(135°) = √(1-cos²(135°)). Here, the value of cos 135° is equal to −(1/√2) . Here, the value of cos 135° is equal to −(1/√2) .
