Answer:
The correct answer is third option. 22 units
Step-by-step explanation:
Points to remember
If a right angled triangle with angles are 45°, 45° and 90° then the sides are in the ratio 1 : 1 : √2
To find the length of one leg of the triangle
From the figure we can see a right angled triangle with hypotenuse = 22√2 units
The other two legs are equal. Therefore the right angled triangle with angles 45°, 45° and 90°
Therefore the given triangle sides are in the ratio,
1 : 1 : √2 = x : x : 22√2
Therefore x = 22 units
The correct answer is third option. 22 units
