The slope of this line is undefined as it is a vertical line.
Hope this helps.
Answer: The sum of the angles of a triangle on a sphere is 180°(1 + 4f), where f is the fraction of the sphere's surface that is enclosed by the triangle. For any positive value of f, this exceeds 180°.
x = -1
Simply get the variable on one side of the equation alone and simplify:
2x = 5 - 21/3
2x = 15/3 - 21/3
2x = -6/3
2x = -2
x = -1

Answer: 60° angle
Step-by-step explanation: AGD is a 90° angle, therefore, subtracting 30 from the 90 degrees gives you 60. As x is vertical to the 60 degree angle and verticals have the same degree measurement, x=60°.
