Question

Find the value of y. 5 8 4 2 50 Pts!

Answer 1

Answer and Explanation:

Since this is a 30-60-90 triangle, you can use the ratio of side lengths specific to this type of triangle:

x = 4√(2)

y = 2(4) = 8

because where 4 = T,

x = T√2    and     y = 2T

so again:

$x = 4\sqrt{2}\\y = 8$

Answer 2

Answer:

• B. 8.

Step-by-step explanation:

All answers verified:

• A. 5. Incorrect. 5 is not long enough for y.
• B. 8. Correct. Just the right size for y.
• C. 4. Incorrect. 4 is already in there, so this is incorrect.
• D. 2. Incorrect. Not even close to fit y.

Your answer is B.
