Hi LUANDATO, Let's take a look at your question. If we look at the bigger triangle, the top angle is a+26. Base angles are 60 and b. Since, sum of all three angles of a triangle is 180 degrees, hence, $$\left(a+26\right)+b+60=180$$ $$a+26+b+60=180$$ $$a+b+86=180$$ $$a+b=180-86$$ $$a+b=94$$ $$a=94-b$$ Therefore, option B is correct. Hope it helps. I am available if you'd like any follow up. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee.
