Question

Does anyone know the answer to this?!

Answer 1

the missing angle is 65

Explanation:

a whole triangle is 180

subtract the given angles from 180

180

- 85

----------

95

subtract the remaining angle

95

- 30

---------

65

~hope this helped :3~

Answer 2

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.
