The angle, its complement, and its supplement are 36, 54 and 144 degrees respectively
<h3>Supplementary and complementary angles</h3>
The sum of complementary angles s 90 degrees while that of supplementary angles is 180 degrees.
Let the complement of an angle be 90 -x and its supplement be 180 -x
If three times the measure of a supplement of an angle is eight times the measure of a complement of the angle, then;
3(180-x) = 8(90-x)
Expand
540-3x = 730 - 8x
540-720 = -8x + 3x
180 = 5x
x = 180/5
x = 36 degrees
Complement = 90 - 36 = 54degrees
Supplement = 180 - 36 = 144 degrees
Hence the angle, its complement, and its supplement are 36, 54 and 144 degrees respectively

Answer: -2.6%
Step-by-step explanation:
Percent error is the difference between the measured and known value, and then we divide by the known value, and then multiply by 100%.
Estimated.number = 15.4 grams.
Actual number = 15.8 grams
Percentage error = (Estimated number - Actual number)/Actual number × 100
= (15.4 - 15.8)/15.8 × 100
= -0.4/15.8 × 100
= 0.0253 × 100
= 2.53
= -2.6% approximately
<h2>
Answer:</h2><h2>The chance is 100 % since we have not seen it in the past three days.</h2>
Step-by-step explanation:
The odds of seeing a black cat are 25% every day.
It also means that the possibility of seeing a black cat is once in 4 days, since 25%
Given, we have not seen one black cat in 3 days.
The chance of seeing a black cat on the 4th day = ?
= 100 % since we have not seen it in the past three days.
