Complementary angles add up to 90 degrees so if y = 8x-20 degrees then the complement of y is 90 - (8x - 20) = 110 - 8x degrees.
x = 6.5y = 16.9
y = 2, 4, 6, 8
y =x^2-x-56 is the same as y = (x + 7)(x - 8)
y=2x2+5. Plug in 0 for x, and you get y=2(0)^2 +5 =0+5=5. 5 is the minimum value for y.
y = 4x - 16At the x-intercept, y=0.0 = 4x - 16Add 16 to each side:16 = 4xDivide each side by 4:x = 4
The complement of an angle is the degree which makes the angle add up to 90 degrees. Therefore: complement of y= 90-53 = 37.

The measure of an angle whose complement is four ninths its supplement?æ is 18 degrees. It is calculated as follows: let y be the angle, its complement will be (90-y) degrees and its supplement will be (180-y)?æ degrees and?æ since it complement is?æ 4/9 its supplement; then?æ it is?æ?æ(90-y)= 4/9(180-y).?æ Hence, you will get 18 degrees when you solve the equation.
If angle A measures X degrees, its complement would be (90 - X) degrees, and its supplement would be (180 - X) degrees. For angle B, if it measures Y degrees, its complement would be (90 - Y) degrees, and its supplement would be (180 - Y) degrees. Thus, the relationships hold true for any angles A and B.
90 -y = complement 180 - y = supplement
360/5 = 72 degrees
The answer is 5 degrees.
Pi radians (180 degrees) is.
a = 3 and y = 0
No. Cosine, along with sec, is an even function. The odd functions are sin, tan, csc, and cot. The reason for this is because is you take the opposite of the y-value for the cosine function, the overall value of the function is not affected.Take, for example, cos(60 degrees), which equals POSITIVE 1/2.If you flip it over the x-axis, making the y's negative, it becomes cos(-60 degrees), or cos(300 degrees). This equals POSITIVE 1/2.Now let's look at an odd function. For example, sin(30 degrees) equals POSITIVE 1/2. Now take the opposite of this.sin(-30 degrees), or sin(330 degrees), equals NEGATIVE 1/2. This is because it is found in the fourth quadrant, where the y's are negative. Sine of theta, by definition, is y divided by r. If y is negative, sine is negative.
To determine the total number of degrees of any polygon, you can use the equation y=180x-360, where x is the number of sides. In your case, it would be y = 180(21) - 360, which equals 3420 degrees.
Very simple, let's mount a linear system: x=measure of the angle; y=supplement; z=complement: I:x+y= 180; II:x+z= 90; III: y+z= 150; Summing I with II we have: I+II: 2x+y+z= 270; III: y+z=150 Now, subtracting III from I+II we have a simple equation: 2x=120; >x= 60< So, the angle whose sum of the measures of its complements and supplement is 150, has 60 degrees.
