The answer to the question is d. irrational
Answer to problem 5 is A) WU = ZX.
Notice how the angle U is between WU and VU. Similarly, angle X is beween ZX and XY
The order is very important. The angles must be between the two pairs of sides.

Answer to problem 6 is C) 15/17.
Use the pythagorean theorem to find the hypotenuse AC to be 17 units. Then take the ratio of the adjacent and hypotenuse to get the answer.

Answer to problem 7 is choice C
Use the rule cos(90-x) = sin(x) where x = 72-a
Answer:
x=4
y=-1
Step-by-step explanation:
x + 2y = 2
-x + y = -5
3y = -3
y = -1
If you would then plug in -1 (for y) then you would get x=4
For example:
x + 2(-1) = 2
x - 2 = 2
x = 4
OR
-x - 1 = -5
-1 + 5 = x
4 = x
x = 4
Answer:
d
Step-by-step explanation:
The answer you eliminated is the right answer which is A
The other rest are wrong because 5x5=25 and 5x5x5=125 if you times both of thos you should get 3125 and A 5x5x5x5x5=3125 Btw i used a calculator.
