#3**0 **

Hey there, Guest!

So as we can see in the picture, the two sides are the same length; therefore, the two bottom angles are also the same.

And as previous knowledge tells us, the sides of a triangle always add up to 180º.

Now, the equation should be:

180°- (74°+74°)

Then, we simplify the equation:

180°- (148°)

And then again:

32

Can we simplify 32/A any further?

The answer is no; therefore, the final answer is 32/A.

Hope this helped! :)
