Oct 2, 2023 · Supplementary angles — combined angle pair equals 180° (straight angle); Reference angle — an acute angle that represents any other angle. Don't hesitate to learn more in the reference angle calculator; and; Central angle — an angle with a vertex at the center of a circle, whose arms extend to the cirlce's circumference. The reference angle is the angle that the given angle makes with the x-axis. When the terminal side of the given angle is in the second quadrant (angles from 90° to 180°), our reference angle is calculated by subtracting the given angle from 180 degrees. So, you can use the formula below: Thus, the reference angle of 120° = 180 - 120 = 60°. It increased to $160,200 in 2023, up from $147,000 in 2022. The Social Security Board of Trustees expects the taxable maximum to reach $167,700 in 2024, but …So the law of cosines tells us that 20-squared is equal to A-squared, so that's 50 squared, plus B-squared, plus 60 squared, minus two times A B. So minus two times 50, times 60, times 60, times the cosine of theta. This works out well for us because they've given us everything. There's really only one unknown.
