x + y = 180; x = 6y + 5 so 6y + 5 + y + 180, ie 7y = 175 so y = 25 and x = 155
The easiest way (for me) to solve this type of question is to put it into an equation in terms of x.Since one angle is 1/4 the size of the other, the two angles would be x and 1/4x, or 4x and x (I suggest using 4x and x).Since the angles are supplementary, their sum is 180 degrees.4x+x=1805x=180x=36 degrees
The 3 interior angles of any triangle add up to 180 degrees
To solve this, use the fact that the sum of all three angles, in a triangle, is 180 degrees.
By measuring them with a protractor will confirm that the 3 acute angles of a triangle add up to 180 degrees.
To solve this class of problems, understand that a triangle has 180 degrees in the interior angles. A quadrilateral has 360. Add 180 degrees for each additional side. The equation is d = 180 * (n-2). For a 16 sided figure, d = 180 * 14 = 2520.Sum of interior angles = (2N - 4) right angles. Here it would be (2 x 16 - 4) right angles = 28 x 90 = 2520 degrees
Supplementary angles add up to 180 degrees. So, if x is the supplementary angle to 148.7 degrees, solve for x: 148.7+x=180 x=180-148.7=31.3 degrees
Supplementary angles add up to 180 degrees You can solve for the supplementary angle first. You can solve for the other directly, but the math is a little more involved. Let A be an angle Start with the supplementary angle. A + ??? = 180 The angle you want is 12 less than twice as big A + (2A - 12) = 180 Solve for A: 3A - 12 = 180 3A = 192 A = 64 Remember A is the supplementary angle, so subtract the angle we solved for (A) from 180 to find the angle you want. 180 - 64 = 116

The 3 interior angles of any triangle add up to 180 degrees
That depends on the specific situation. For example:* Adjacent angles add up to the larger, combined, angle. For instance, if you divide a straight line into two or more angles, the angles add up to 180 degrees. * The angles of a triangle also add up to 180 degrees.
To solve this, use the fact that the sum of all three angles, in a triangle, is 180 degrees.
By measuring them with a protractor will confirm that the 3 acute angles of a triangle add up to 180 degrees.
Simple: one is 26 deg and another is 80 deg. You cannot solve anything else because you do not even know what the shape is!
Complimentary angles add to 90 degrees. So, x + y = 90. Also, we know the difference is 12 degrees. So, x - y = 12. (Note that it really doesn't matter which angle corresponds to x and y. The way it is set up here is x is the larger angle.) Now solve the system: x + y = 90 x - y = 12 2x = 102 x = 51 y = 90 - 51 = 39 So the two angles are 51 degrees and 39 degrees.
Well if it has 180 degrees over all, and the two base angles have to be congruent, then the equation is 180-120=2x or each base angle is 30 degrees.
To solve this class of problems, understand that a triangle has 180 degrees in the interior angles. A quadrilateral has 360. Add 180 degrees for each additional side. The equation is d = 180 * (n-2). For a 16 sided figure, d = 180 * 14 = 2520.Sum of interior angles = (2N - 4) right angles. Here it would be (2 x 16 - 4) right angles = 28 x 90 = 2520 degrees
To find the sum of interior angles for any N-sided polygon = N*180° - 360°Solve the equation: N*180° - 360° = 3060°, for N, and N = 19
