Answer:
122 degs
Step-by-step explanation:
If that angle is 148 degs, and if the angle next to it is supplementary, that means that you can do 180 - 148 to find the angle next to the given.
The angle by the 148 is therefore 32.
It shows that the 32 + another angle is 90 degs because of the symbol, so the angle by it is 90 -32 = 58.
If the triangle is isosceles, that means that the angle by the x is also 58, due to the two hashes through two legs of the triangle.
If they are also supplementary, you can do 180 - 58 to find the answer.
122.
You can do some other methods, such as using the isosceles legs theorem or something I forgot to find x quickly.
