Find x and y.
- A.
X = 5*sqrt(2), and y = 5*sqrt(2)
- B.
X = 5*sqrt(3), and y = 5
- C.
X = 5, and y = 5*sqrt(2)
- D.
X = 5, and y = 5*sqrt(3)
Correct Answer
D. X = 5, and y = 5*sqrt(3)Explanation
The ratio of the sides of a 30-60-90 triangle are x, x*sqrt(3), and 2x (listed in order of the side opposite the 30,60,90).Rate this question:
-
- 3.
No matter what positive number x is, x*sqrt(3) is LARGER than 2x.
- A.
True
- B.
False
- C.
Depends on what positive number x is.
Correct Answer
B. FalseExplanation
sqrt(3) is roughly 1.732, so when you multiply a number by 1.732, that's LESS than multiplying that number by 2.
That's why "2x", the LARGER number, is across from the right angle, the LARGEST angle.Rate this question:

- A.
X=70*sqrt(2), and y=70
- B.
X=140, and y=70*sqrt(3)
- C.
X=70*sqrt(3), and y=140
Correct Answer
B. X=140, and y=70*sqrt(3)Explanation
The ratio of the sides of a 30-60-90 triangle are x, x*sqrt(3), and 2x (listed in order of the side opposite the 30,60,90).Rate this question:
