how do i do this could you show step by step please?

The value of x from the given right triangle in rational form is 14√
This is a way of determining the sides and angles of a right triangles
From the given triangle
Opposite = 7√4 = 14
Hypotenuse = x
acute angle = 45 degrees
Using the theorem
sin 45 = 14/x
x = 14/sin45
x = 14√2
Hence the value of x from the given right triangle in rational form is 14√2
