Question 1 - Answer:
Angle bisector – ray that divides an angle into two congruent adjacent angles. Triangle – the figure formed by three segments joining three noncollinear points. Each of the three points is a vertex of the triangle and the segments are the sides.
Question 2 - Answer:
Two adjacent angles whose noncommon sides are opposite rays. Two angles whose measures sum to 90 degrees. Two angles whose measures sum to 180 degrees. If two angles form a linear pair, then they are supplementary.
Question 3 - Answer:
The sides of a right triangle have different names: The longest side, opposite the right angle, is called the hypotenuse. In the diagram, the hypotenuse is labelled c. The other two sides are called the legs of the triangle.
Answer:x-4
Step-by-step explanation:because (-1)x(-1)=1
Answer:
Step-by-step explanation:
If in doubt, multiply them out.
(-i)^4 = i^4 = 1 . . . . . results for ±i
(-1)^4 = 1^4 = 1 . . . . . results for ±1
An even power of a negative number is equivalent to the same power of the opposite (positive) number. The even number of minus signs cancel in the final product.
_____
In trig form, unity is 1∠(n·360°) . . . . . for n = any integer
Then the 4th root is ...
1^(1/4) ∠(n·360°/4) = 1 ∠(n·90°) . . . . for n = 0...3 (angles repeat after that)
That is, the roots are ...
- 1∠0° = 1
- 1∠90° = i
- 1∠180° = -1
- 1∠270° = -i
Of these, all but the first are listed among your answer choices. The appropriate selection is <em>all of the above</em>. (recognizing that not all of the appropriate choices are "above" that answer selection).
Answer:
because the 3 in(3,5) is the x and the 3 in (5,3) is the y
6
her order can't exceed 100
and if she buys 2 she gets 1 free
each one costs 22
so she can get 6 skirts for 88 which is the highest it can go
