Answer:
3 in²
Step-by-step explanation:
The fraction 9/16 is equal to the equation 9 ÷ 16.
9 ÷ 16 = 0.5652
Lets find the square root of 0.5652
So the length of one side is 0.75 in²
Now we'll multiply this by 4, for the length of the 4 equal sides.
0.75 x 4 = 3.
This means the perimeter is 3 in².

Answer:
D. x = 15; y = 5√3
Step-by-step explanation:
You don't need to know any trig to select the correct answer. You only need to know that the lengths of both sides must be less than the length of the hypotenuse. It is also helpful to know that √3 is about 1.732, so 10√3 ≈ 17.32.
Since x < 10√3, only answer choices A and D are viable.
Since y < 10√3, only answer choice D is viable.
_____
If you want to solve this using trig relations, you can recall that the sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. This means short side y is half the length of the hypotenuse 10√3, so y = 5√3. It also means longer side x is √3 times y, so is x = (5√3)√3 = 5·3 = 15.
x = 15; y = 5√3
