When a bush was first planted in a garden, it was 20 cm tall. After two months, it was 300% as tall as when it was first planted. Use mental math to find how tall the bush was after the two months.

Length of the bush after 2 months = 60 cm

Step-by-step explanation:

When the bush was planted in the garden, height of the bush = 20 cm

200% as tall as initial length = 2 times of the initial length

300% as tall as initial length = 3 times of the initial length

Therefore, after 2 months, length of the bush = 20 × 3

                                                                            = 60 cm

After 2 months, length of the bush is 60 cm.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
