Answer:
17
Step-by-step explanation:
Given expression;
(x - 2)² + 8² = x²
To solve this problem, expand the expression in the parentheses;
(x- 2)(x -2) + 64 = x²
( x² - 2x -2x + 4) + 64 = x²
x² - 4x + 4 + 64 = x²
x² - 4x + 68 = x²
Collect like terms;
x² - x² - 4x + 68 = 0
-4x = -68
x = 
= 17
If you looks at the well drawn picture that I drew, you'll notice that we notice that we can use the trigonometric ratio
tan; in this case:
tan58=
Solving this, we get:
x=
Which gets us that
x=6.25 (approximately)
(It really wasn't that great of a picture but still :D)
:)
Simply both the 5s to -25 and do -(-3/25) the answer would be 3 over 25
