The answer is -6
because the triangle angles must measure to 180 and the scalene triangle states that the base angles add up to 86. Subtract 86 from 100, you get 94. Angle two is 94. 94-100=x
Statistical questions: A, C, E, because they all talk about students, where B and D talk about adults and people in general. Frank just wants to know about students.
Since the equations for area is A= L*W
A= 9*4= 54
Replace X with 3 and simplify. The answer you would get is 11.
