We know that all triangles have a sum of 180 degree. If one angle of a triangle is greater than 90 degrees than we conclude that:
1. It is an obtuse triangle
2. It will have one obtuse angle(greater than 90 and two acute angles(less than 90))
2. It is not a right triangle(which has one angle of 90 degree)
3. It is not an equilateral triangle(in which all angles are equal)

The expression used in this question, 0.99c + 0.79a, is representative
of the total cost of buying any number of apples and cucumbers, Where x =
how many, 0.99c is the total cost of cucumbers when c is given as a
value, and 0.79a is the total cost of apples when a is given as a value.
Answer:
The answer would be x= -2
