Step-by-step explanation:
The first step to do is make a single triangle from the problem. That triangle can be BDH. We do still need the line BE, although that can wait.
Now find the last angle of the triangle. The sum of angles of a triangle always equal 180, so we can easuly find the missing angle.
So the missing angle is 109°. Now we can find the value of x.
We can use that angle because it sits right next to x on the same line. A line is 180° at any node as long as the line continues straight, so we simply subtract the angle we just found to find x.
Now we know x is 71

Step-by-step explanation:
Not knowing what properties you have to choose from, it'll be one that looks like ;
The base (a) stays the same;
the Numerator in the exponent is the exponent on the base;
and the Denominator in the exponent is the index (root number) of the radical.
