Answer:

65°

Explanation:

Properties of a triangle:

  • Triangles always have 3 sides
  • The sum of the interior angles of a triangle must be equal to 180°.

To solve:

  • Since the angles inside of a triangle must always be equal to 180, use the following formula to solve:
  • a + b + c = 180
  • (The variables can be assigned to any value in this situation)
  • Since two angles are already given, replace 2 variables:
  • a + 85 + 30 = 180
  • Solve the equation by subtracting on both sides:
  • a = 65
  • The value of a is the measure of the missing angle. The problem is solved.
