Answer:
x is equal to -10 degrees.
Explanation:
To solve for x in the given angles, we need to find the value that makes the sum of the angles equal to 180 degrees.
Given angles:
1. 65°
2. 40°
3. x + 85°
To find x, we can set up the equation:
65° + 40° + (x + 85°) = 180°
Combine like terms:
(65 + 40 + 85)° + x = 180°
Simplify:
190° + x = 180°
To isolate x, we subtract 190° from both sides:
x = 180° - 190°
Simplify:
x = -10°
Therefore, x is equal to -10 degrees.
