Answer:
the answer is 28°
Step-by-step explanation:
opposite angles or vertical angles because the 2 lines intersect each other.
<DSR + <SRD + <RDS = 180° (Angle sum property)
2x + x +3x = 180°
6x = 180°
x = 180°/6
x = 30°
So, <SRD = x = 30°
<RDS = 3x = 3(30°) =90°
<DSR = 2x = 2(30°) = 60°
Hope it helps !

Add the total faces: 30 + 20 + 12 = 62
Using the given equation: V + F = E +2
You have F = 62, V = 120
Now solve for E:
120 + 62 = E +2
Simplify:
182 = E +2
Subtract 2 from both sides:
E = 182 - 2
E = 180
It has 180 edges.
