38°

Step-by-step explanation:

The angles in a triangle always add up to 180 degrees.

Therefore, all the angles in the triangle given in the question add up to 180 degrees.

So, let's create an equation and solve for :

Simplify:

Solving for we get:

Now, let's put the value of we got into the formula for angle A.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
