A quadrilateral has four angles. There is information on only three so there are infinitely many possible answers.
There are two things missing. How large are the known sides and what are the measures of at least one of the other angles.
Let's assume the measure of the first angle is x degrees. The second angle is one-third as large as the first, so its measure is (1/3) * x = x/3 degrees. The third angle is two-thirds as large as the first, so its measure is (2/3) * x = 2x/3 degrees. Therefore, the measures of the angles in the triangle are x degrees, x/3 degrees, and 2x/3 degrees.
Suppose one angle is x and the other angle is 14x. Supplementary angles add to 180o, so x+14x = 180 15x = 180 x = 180/15 x = 12. The required angle is 12o. Check: The second angle will be 14*12 = 168. 168+12 = 180, so the large angle is the supplement of the small one.
To find the measure of an angle, you need to know the size of the entire angle and the other angles within the angle. Then, you subtract the smaller, known angles from the entire, large angle and you should get the measure of the missing angle.
Supplementary angles are angles which add to 180o. So, one angle is nine times as large as the other, therefore letting the smaller angle be X, we have the following: 9X + X = 180 10X = 180 X=18o and the other is 9 times this amount or 162o
Supplementary angles - two angles that add up to 180 degrees. No matter how large or small angles 1 and 2 on the left become, the two angles remain supplementary which means that they add up to 180°. By the way, supplementary angles do not need to be adjacent angles(angles next to one another) if it doesnt add up to 180 then they are not supplementary angles, but if they do then they are supplementary angles.
A+b=180 x+2x=180 3x=180 x=60

Congruent angles have the same measure. congruent Kenpachi54 improve answer: Actually, angles don't have to be congruent just to have the same angle measurements A has a right angle is 90 degrees. even if there is a small right angle and a large right angle you know they are both 90 degrees because ALL right angles are 90 degrees, so there is really no name for it.
No, they both have right-angles.
First angle=X Second angle=4x Third angle=5X-45 Since the angles of a triangle always = 180o x+(4X)+(5X-45)=180o 10X-45=180 10X=225 X=22.5 Therefore. . . First Angle=X=22.5o Second Angle=4X=90o Third Angle=5X-45=67.5o
Complimentary angles are two angles that add up to 90o. It the sum of two angles is 90o, and one is twice as big as the other, then we can make up a little equation to solve for that larger angle (a). It might look like this: 90o = a + ( a / 2 ) As our larger angle (a) was said to be twice as large as our smaller angle, our smaller angle (a/2) is half as large as the larger angle. 90o = 3a / 2 180o = 3a a = 180o / 3 = 60o Our mystery angle is a 60o angle. The smaller one is 30o. The larger angle is twice the smaller, and they two sum to 90o. Our work checks.
