2. See the figure below. What is the exact length of x? x = _______ units


Please explain how you got the answers.

Answer 1

Answer:

I only got 2) 5.5units

Step-by-step explanation:

ΔACD is a 45°-45°-90° triangle so if we apply the rule for that triangle:

AD = 11√2

AC = DC = 11√2 ÷ √2 = 11

ΔABC is a 30°-60°-90° triangle so if we apply the rule of that triangle:

AC = 11

x = CB = AC/2 = 11/2 = 5.5

so x=5.5un.

Hope this is correct and hope it helps :)

Answer 2

Answer:

2) 5.5units because vvvvvvv

ΔACD is a 45°-45°-90° triangle

AD = 11 {square root of 2}

AC = DC = 11√2 ÷ √2 = 11

ΔABC is a 30°-60°-90° triangle so if we apply the rule of that triangle:

AC = 11

x = CB = AC/2 = 11/2 = 5.5

so x=5.5
