Answer (13 of the original arrangements are duplicates now, as
AAAF F F FDDDDCC, AAF F F FDDDDCCA, ..., CAAAF F F FDDDDC
are identical): 900900/13 = 69300.
All the triangles have 180° total angle measurement.
First question:
114 + 37 + x = 180°
151 + x = 180
x = 180 - 151
x = 29°
Second question:
93 + 46 + x = 180
139 + x = 180
x = 180 - 139
x = 41°
Answer:
75
Step-by-step explanation:
If there is 6 even numbers and 6 odd numbers, then the spinner would land on an even number half the time. Half of 150 is 75 so the answer is 75.
1 + 3 = Δ + 3
By comparing
Δ = 1.
