The angles are supplementary ===> A + B = 180 ===> A = 180 - B. Next statement: 3A = 2B - 5 (We don't know or care yet which one is larger, nor do we need to. That will come out on its own.) Substitute the first into the second: 3(180-B) = 2B-5 ===> (540-3B) = (2B-5 ) ===> 540 = 5B-5 ===> 545 = 5B109 = B ===> 71 = A

Complementary angles are angles that add up to 90 degrees. If the smaller angle is x, the larger is 5x, so 6x = 90. X equals 15, and the larger angle measures 75 degrees.
Supplementary angles add up to 180° Let the smaller angle be x, then the larger angle is x + 70°, and: x + (x + 70°) = 180° → 2x + 70° = 180° → 2x = 110° → x = 55° → x + 70° = 55° + 70° = 125° Thus the two angles are 55° and 125°. Therefore the angle you want is the larger at 125°.
When 2 or more angles add up to 180 degrees they are said to be supplementary. Supplementary angles only occur on straight lines, so if one angle is said to be 120 the other angle has to be 60 degrees in order to form a straight line and also to add the angles to 180 degrees
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.
180 - 35 = 145. Half of 145 is 72.5 which is the smaller angle. (The other angle is 35 + 72.5 ie 107.5)
It is 125o Let the larger angle be α then the smaller is 2/5α + 5o; and α + (2/5α + 5o) = 180o ⇒ 7/5α = 175o ⇒ α = 125o
the larger angle is 60 and the smaller angle is 30.complimentary angles are 2 angles forming 90 degrees.
112.5 degrees
Supplementary angles are two angles whose measures add to 180 degrees. Adjacent angles are two angles that happen to lie next to each other, so that they combine to form a larger angle whose measure is the sum of the measures of the adjacent angles. Angles may be both adjacent and supplementary, in which case they will form a straight angle.
The two angles are 158o and 22o Two supplementary angles add up to 180o Let the smaller angle be x and the larger y, then: y = 7x + 4o x + y = 180o → x + (7x + 4o) = 180o → 8x = 176o → x = 22o ← y = 7 x 22o + 4o = 158o
Two supplementary angles add up to 180 degrees. If one measures 60 less than the other, they must be 60 and 120 degrees, so the measure of the larger angle is 120 degrees. To find that algebraically, where m is the larger angle: m+(m-60)=180 2m=240 m=120

Complementary angles are angles that add up to 90 degrees. If the smaller angle is x, the larger is 5x, so 6x = 90. X equals 15, and the larger angle measures 75 degrees.
For any given angle, its supplementary angle is 90 degrees larger than its complementary angle.
Supplementary angles add up to 180° Let the smaller angle be x, then the larger angle is x + 70°, and: x + (x + 70°) = 180° → 2x + 70° = 180° → 2x = 110° → x = 55° → x + 70° = 55° + 70° = 125° Thus the two angles are 55° and 125°. Therefore the angle you want is the larger at 125°.
