aivan3 [116]

Answer: x = 5

Explanation:

2(5x + 2) = 54
10x + 4 = 54
10x = 54 - 4
10x = 50
x = 50/10
x = 5

Therefore, x = 5

$DC=AC-AD=20-16=4$

<u>Question</u><u> </u><u>2</u>

By the geometric mean theorem,

$BD^2 = (4)(16)=64 \\ \\ BD=8$

<u>Question</u><u> </u><u>3</u>

By the Pythagorean theorem,

$AB^2 = 8^2 + 16^2 \\ \\ AB^2 = 320 \\ \\ AB=8\sqrt{5}$

<u>Question</u><u> </u><u>4</u>

By the Pythagorean theorem,

$BC^2 = 8^2 +4^2 \\ \\ BC^2 = 80 \\ \\ BC=4\sqrt{5}$
