If all three angles are exactly the same measure, how big is each angle?
Hint: x + x + x = 180
(a)
Which two angles are the interior angles?
Angle X and Angle Y
Angle X and Angle Z
Angle Y and Angle Z
Angle Z and Angle W
Which angle is the exterior angle?
(a)
What is the measure of x?
101°
111°
121°
131°
Find the indicated angle measure. (What is ?)
(a)
Set up an equation to find x.
42 + 8x = 2 + 12x
2 + 12x + 42 = 8x
42 + 8x + 2 + 12x = 180
42 + 8x = 180
Set up an equation to find x.
52 + 5x + 16 + 10x + 8 = 180
52 - 5x + 16
52 + 5x + 16 = 10x + 8
52 + 10x + 8 = 5x +16
Solve for x.
