Answer:
30
Step-by-step explanation:
In this picture, the angle, 30 degrees, is a part of the whole. we are looking for the value of X.
First we can take off 45 degrees, since the angle is lower than 30 degrees
Now we can take off 15 degrees, since the angle is too small.
And we can also take off 10 degrees since its way too small.
2x mean 2 times X.
The overall measurement is a 90 degree angle, indicated by the box.
90-30= 60
30 * 2 = 60.
The correct answer is 30.
