Which of the following statement is true?
a. Two adjacent angles can be complementary
b. Two adjacent angles cannot be supplementary
c. An acute angle cannot be adjacent to an obtuse angles
d. Two right angles cannot be adjacent angles
Answer from: stacykon
a. Two adjacent angles can be complementary
This is another way of saying two angles next to each other add to 90 degrees. In other words, two angles touching each other forming a corner.
Two adjacent angles can be supplementary, so choice B is false.
An acute angle is always adjacent to an obtuse angle, so choice C is false.
Two right angles can be adjacent, and they would form a straight (180 degree) angle, so that's why choice D is false.

Aking and his army will attempt to capture a fortress. the left and right flanks break off from the main group to attack the west and east guard towers. suppose the left flank has a 60% chance of success and the right flank has a 75% chance of success, independently of one another. if both flanks capture their respective targets, then the king has a 98% chance of successfully taking the fort. if, however, only the left flank captures its tower, the king has an 80% chance of success; if only the right flank succeeds, the king has a 50% chance. if both flanks fail, then the king's chance of capturing the fort drops to 20%. it turns out the king captures the fort. what is the probability that one, and only one, flank was successful (either the left, or the right, but not both)? (round your answer to 3 decimal places)
