Find the lengths of the missing sides in the triangle. Write your answers as integers or as decimals rounded to the nearest tenth. The diagram is not drawn to scale.
triangle has sides 7, Y and X and 45 degree angle
can someone show me how to do this? im supposed to use trig ratios.

Is this a rightangled triangle?
If not, where is the 45° angle?
