Answer:
B
Step-by-step explanation:
The sum of the 3 interior angles of a triangle = 180°
Check the sums of the given sets of angles
90° + 42° +58° = 190° ≠ 180° ← not valid
60° + 60° + 60° = 180° ← Valid
100° + 48° + 42° = 190° ← not valid
31° + 75° + 70° = 176° ← not valid
answer: 2,880
explination: my program marked it as correct
It's fraction form, 4.02 = 402/100 = 201/50
In mixed form, 4 1/50
80 kilometers is equal to 80,000 meters. This is greater than 1000 meters.
4(a-2)=3(a+4)
4a-8=3a+12
a=20
