Answer:
60 degrees
Step-by-step explanation:
The two legs are not equivalent pointing to a 30-60-90 triangle which means x=60 degrees
This is asking for the sine. The sine is found by taking the opposite side and divinding it by the hypotenuse.
sine=7
hypotenuse-9
7/9 or .777 (i use a sine/cosine/tangent chart to find the degrees)
answer=51°
