180 - 74 * 2 = 32 so A
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:
Then, we simplify the equation:
And then again:
Can we simplify 32/A any further?
The answer is no; therefore, the final answer is 32/A.
Hope this helped! :)
