Supplementary angles will always add up to 180. If you had a straight line, and you drew another line across that line, the two angles on either side of that line would add up to 180 because a flat line is equal to 180 degrees.

Answer: True</h3>
If you know the population standard deviation (sigma), then you use the Z distribution. If sigma is not known, then you use the T distribution.
Side note: Even if sigma is not known, you could use the Z distribution if the sample size n is greater than 30. If n > 30, then the T distribution is approximately about the same as the Z distribution.
Answer: 35° and 55°
Step-by-step explanation:
For complementary angle, their total value equals to 90°.
Let the measure of the angle be y.
Therefore the complement will be:
= 90° - y
The measure of an angle plus twice its complement is equal to 145 can be expressed as:
y + 2(90 - y) = 145
y + 180 - 2y = 145
y = 180 - 145
y = 35°
The angle is 35° and its complement will be:
= 90 - y
= 90 - 35
= 55°
