If both triangles ABE = CBD then <C = <A
Hope it helps.
3 7/8 because looking at the ruler, the line is 7 of the 8. hope that’s helps!
(3x + 5)° + (10x - 7)° = 180°
13x + (-2) = 180
13x = 180 + 2
13x = 182
x = 14
∠QRT = 3 * 14 + 5 = 42 + 5 = 47°
∠TRS = 10 * 14 - 7 = 140 - 7 = 133°
Here a photo of the answer. The first thing you have to do is split the figure into separate shapes. Find the area of the shapes, then add them all together.
30, you can devide 135 by 4.5
