Assuming the angles are expressed in degrees:
P = 2Q -3°
(because "angle P is three less than twice the measure angle Q")
P + Q = 180°
(because they are supplementary angles)
P+Q = 2Q - 3° + Q = 3Q -3° = 180°
3Q = 183°
Q = 61°
P = 2∙61° -3° = 122° - 3° = 119°
If the angles are expressed in radians, the math is similar except you start with
P = 2Q - 3 and P+Q = π
yielding
P = 2π/3 -1 and Q = π/3 +1

What is The measure of an angle is 20 and deg. What is the measure of its supplement?
Its supplementary angle is 160 degrees because supplementary angles add up to 180 degrees
Can a exterior angle be found through the use of complementary angles?
false but You can find the measure of an exterior angle by using supplementary angles.
An angle with a measure of 180 is called a(n) angle.?
Supplementary angles add up to 180 degrees
What angle is supplementary to a 110 degree angle?
Supplementary angles are angles whose sum is 180° . The supplementary angle to 110° is therefore 70°.
If in angle A plus measure angle B equals 180 then angle A and angle B are?
The angles are supplementary if they have a sum of 180 degrees.
What is a supplementary angle and what does it measure?
Supplementary angles are two angles that measure up to 180 degrees. EXAMPLE: If the an angle measures 70 degrees, to find the missing angle, you subtract 70 from 180 because supplementary angles equal 180 degrees. Your answer (in this case 110) is the answer for the measure of the missing angle.
2 angles are supplementary The measure of one angle is 115 what is the measure of the other angle?
???
What is the measure of angle A if angles A and B are supplementary and angle B is 104?
76
What is the measure of an angle supplementary to an angle that measures 101 degrees?
Supplementary angles are angles that add up to 180 degrees, ie. a straight angle. Therefore, the angle supplementary to 101 degrees would be 180-101=79 degrees.
If the measure of an angle is 4 times its supplementary angle what are the angles?
An angle and the angle that it is supplementary to have a total measure of 180 degrees.Let x be the supplementary angle. 4x would be the original angle.x + 4x = 1805x = 180x = 364x = 144So the two angles are 144 degrees and 36 degrees.
What is The measure of an angle is 20 and deg. What is the measure of its supplement?
Its supplementary angle is 160 degrees because supplementary angles add up to 180 degrees
What is the measure of an angle that is supplementary to an angle that measures 80?
Supplementary angles add up to 180 degrees so it is 100 degrees
What is the measure of supplementary angle?
Two supplementary angles add up to 180 degrees.
The supplement of a 65 degree angle has a measure of?
Supplementary angles are angles whose sums =180 degrees. You have a 65 degree angle + it's supplementary angle = 180 degrees. So, to find the supplementary angle, subtract 65 from 180. 180 - 65 = supplementary angle. 115 = supplementary angle. To check, add the angles together. 65 + 115 = 180 (check) (Also, you might be working with complimentary angles. Complimentary angles are angles whose sum = 90 degrees.)
If two angles are congruent, adjacent, and supplementary. What is the measure of each angle?
90 degrees is the angle
What angle measure 180?
Supplementary angles add up to 180 degrees
If 2 angles measure 180 degrees what is the angle?
Is it not a supplementary angle. A complementary angle is 90 degrees, so I think that supplementary would be 180 degrees.
