<span>The line of symmetry of the triangle bisects the right angle and the diagonal of the square.
The line is 1/2 the length of the square's diagonal :

(1/2)(10√2) = 5√2. 

</span>Let CG be a distance x from the vertex of the right angle in the triangle.
Remaining distance = 5√2 - x. 
<span>
(1)(x) = (2)(5√2 - x)</span>
x = 10√2 - 2x
<span>3x = 10√2 </span>
<span>x = (10/3)√2. 
</span>
Using Pythagorean theorem,
x^2 + y^2 = c^2
 
<span>c = (10/3)√2,
and x = y,
so 2x^2 = 200/9
x = √(100/9) = 10/3 = y. 
</span>
<span>x = y = 3.333</span>

Solve the following inequality.
Crazy boy [7]

Answer:

A -6 < x ≤ -3

Step-by-step explanation:

21 ≤ - 3(x - 4) < 30

Divide all parts by -3.  Remember that flips the inequalities

21/-3  ≥ - 3/-3 (x - 4) > 30/-3

-7  ≥  (x - 4) > -10

Add 4 to all sides

-7+4  ≥  x - 4+4 > -10+4

-3  ≥  x  > -6

Rearranging the order

-6 < x ≤ -3
