An angle in standard position with a positive measurement less than 180° will extend below the x-axis.
a. true
b. false

In plotting the angle in a Cartesian plane, the first quadrant is for angles greater than zero to lower than 90 degrees. The second quadrant is for angles greater than 90 degrees to 180 degrees. Then, the third quadrant is for angles greater 180 to 270 degrees. Lastly, for angles 270 to 360 are in quadrant IV. Therefore, the angles with measurement less than 180 degrees will always lie above the x-axis. The answer is letter B. False. 

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
