Answer:
x = 5
Step-by-step explanation:
You want to find x such that ...
x^2 +(x +1)^2 = 61
2x^2 +2x -60 = 0 . . . . . simplify, subtract 61
x^2 +x -30 = 0 . . . . . . . divide by 2
(x +6)(x -5) = 0 . . . . . . . . factor; solutions will make the factors be zero.
The relevant solution is x = 5.
Given:
The ratio of 45-45-90 triangle is 
.
The hypotenuse of the given isosceles right triangle is 
.
To find:
The lengths of the other two sides of the given isosceles right triangle.
Solution:
Let 
be the lengths of the other two sides of the given isosceles right triangle.
From the given information if is clear that he ratio of equal side and hypotenuse is 
. So,
Therefore, the lengths of the other two sides of the given isosceles right triangle are 7 units.
