Which type of triangle is it possible for an obtuse triangle to be? a. acute triangle b. equilateral triangle c. isosceles triangle d. right triangle

The answer would be C. isosceles triangle, because obtuse is the opposite of acute, equiateral triangles cannot be obtuse, and right triangles have the angles of 90, 60, and 60.

If you're familiar with the quadratic equation


well, is the x component of the vertex, in your case, the vertex is the highest point

figure out what t is at the highest point, and then substitute that back into the equation in order to determine height

x=t in this problem
