Right triangle has one degree = 45 so it's isosceles right triangle.
let y = hypotenuse of small isosceles right triangle
y^2 = 7^2 + 7^2
y^2 = 49 + 49
y^2 = 98
so
x^2 = 98 + 98
x^2 = 196
x = 98
answer
x = 98
Answer:
![\left[\begin{array}{cccc}1&3&4&5\&3&1&5&6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D1%263%264%265%5C%263%261%265%266%5Cend%7Barray%7D%5Cright%5D)
The only ones are on the "diagonal", where i = j. Else the position is simply the sum.
Answer: I think that the answer is 100.
Step-by-step explanation: the line is straight and horizontal, and straight horizontal lines r 180 degrees, we already have 80 degrees so X is 100.
