Study Notes
Finding the Value of X
- Triangle UVW has angles measuring 30°, 24°, and (3x - 9)°.
- The sum of the angles in a triangle is 180°.
- Therefore, 30° + 24° + (3x - 9°) = 180°
- Simplifying the equation: 54 + 3x - 9 = 180
- 45 + 3x = 180
- 3x = 135
- x = 45
Finding Angle BAC
-
Lines p and q are parallel.
-
Angle FCB is 35°.
-
Angle FCD is 70°.
-
Angle BCD is 110°.
-
Angle BAC = ?
-
Angle ACB and angle BCD are supplementary angles, so angle ACB = 180° - 110° = 70°
-
Triangle ABC has side AB, AC, BC.
-
Angle ABC = 70°.
-
Angle BAC + Angle ACB + Angle ABC =180°
-
Angle BAC + 70 ° + 70° =180°
-
Angle BAC = 40°
