The dimensions of the length of the legs are 15 m and 20 m in the given right triangle.
Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
Let x be the length of one of the legs. Then the length of the other leg is 2x-10m. We can use the Pythagorean theorem to find the lengths of the legs.
We can write this as an equation:
x² + (2x - 10)² = 25²
5x²- 40x + 100 = 625
5x²- 40x + 100 - 625 = 0
5x²- 40x - 525 = 0
Divided by 5 into the above equation,
x²- 8x - 105 = 0
After solving the above quadratic equation, we get
x = 15 and x = -7
Take x = 15 as the length of one of the legs.
So, the length of the other leg is 2(15)-10 = 20 m.
Thus, the dimensions of the length of the legs are 15 m and 20 m.

Answer:
XY ≈ 9.2 m
Step-by-step explanation:
using the cosine ratio in the right triangle
cos58° = = = ( multiply both sides by XY )
XY × cos58° = 4.9 ( divide both sides by cos58° )
XY = ≈ 9.2 m ( to the nearest tenth )
