Suppose the angle is x then the second is 5x. The two angles are supplementary so x + 5x = 180 or 6x = 180 so that x = 30 degrees.
To find the perimeter of a triangle you have to add up all the sides. So to find the perimeter of this triangle you just add 2x+5x+6x=13x. To find the actual perimeter you would have to know what x equals
2sin2(6x) + 3sin(6x) + 1 = 0 Solving the quadratic, sin(6x) = -1 or sin (6x) = -0.5 sin(6x) = -1 => 6x = 45+60n degrees for integer n sin(6x) = -0.5 => 6x = 35+60n or 55+60n degrees for integer n.
find the number with the highest exponent, that exponent is the degree. for example, 2x to the 3rd power + 6x to the 2nd power the degree is 3
(180 - x) / (90 - x) = 7Multiply each side by 7:180 - x = 630 - 7xSubtract 180 from each side:- x = 450 - 7xAdd 7x to each side:6x = 450Divide each side by 6:x = 75The angle is 75 degrees.Its supplement is 105 degrees.Its complement is 15 degrees.Check: 105/15 = 7 yay!
x + 2x = 6x = 180 9x = 180 9x/9 = 180/9 x = 20....theres you answer
6x what = 180
If the two expressions given for the vertex angle are to be the same number, 6x + 8 = 9x -25; then 3x = 25 + 8 = 33 and x = 11. Therefore, the vertex angle is 6(11) + 8 = 74. The two base angles of an isosceles triangle must be the same and the three angles of the triangle must sum to 180. Therefore, calling the unknown base angle y, 2y + 74 = 180, or y equals 53.
In parallelogram ABCD, angle A and angle D are adjacent or consecutive angles and are supplementary, meaning the sum of their measures is equal to 180 degrees. Angles A and C are opposite angles and have the same measure. These are some important properties of parallelograms. So to find the measure of angle C, you first have to find the measure of angle A. You can do that with a little algebra. First, set the expressions for the measures of angles A and D equal to 180 and solve for x. Then plug that value for x into the expression for the measure of angle A, which is the same as the measure for angle C. 5x + 30 + x = 180 6x + 30 = 180 6x = 150 x = 25 Therefore, 5x + 30 = 5(25) + 30 = 125 + 30 = 155 The measure of angle C is 155.
Suppose the angle is x then the second is 5x. The two angles are supplementary so x + 5x = 180 or 6x = 180 so that x = 30 degrees.
X = 180 - Y so 180 - Y = 2x + 4 and Y = 4x + 20 so 180 - 4x - 20 = 2x + 4 therefore 6x = 156 so x = 26 making Angle X = 56o and Angle Y = 124o

The easiest way would be 6x(6x6-6)
130 Degrees180-24=156So you know that the sum of all the angles is 180, so the sum of the other two angles is 156. You Know that angle p is equal to some number x. And you know the angle n is five times some number x or 5x. You know the sum of the two angles numerically and algebraically.6x=156x=26n=5xn=5(26)n=130
