Equilateral triangles have three equal angles, so we right away know that x=60º. Then, we just solve (3(60)-70)º, which is 110º, for the answer.
Answer: 2.225 kg
Step-by-step explanation:
You know that:
- The total weight the farmer sold was 8.9 kilograms.
- 3/4 of this weight is apples, and the rest is pears.
Therefore, to calculate the amount of kilograms of pears she sold at the farmer's market (which you can call x), you need to apply the following proccedure.
Thefore, you obtain the following result:

Multiples of 12 : 12 , 24 , 36 , 42 , 60 , 72 , 84 , 96 , 108 , 120
3 left (+3) : 15 , 27 , 39 , 45 , 63 , 81 , 87 , 99 , 111 , 123
Multiples of 9 : 09 , 18 , 27 , 36 , 45 , 54 , 64 , 72 , 81 , 90
21 left (+21) : 30 , 39 , 48 , 57 , 66 , 75 , 85 , 93 , 102, 111
