Answer 1

Percentage of Land Occupied by Currants, Raspberries, and Gooseberries

According to the information provided, 25% of the land is occupied by currants, 45% is occupied by raspberries, and the remaining portion is occupied by gooseberries. To determine the percentage of land occupied by gooseberries, we need to subtract the percentages of land occupied by currants and raspberries from 100%.

Let's calculate it step by step:

1. Percentage of land occupied by currants: 25% 2. Percentage of land occupied by raspberries: 45% 3. Percentage of land occupied by gooseberries: 100% - (25% + 45%)

To find the percentage of land occupied by gooseberries, we subtract the sum of the percentages of currants and raspberries from 100%.

Percentage of land occupied by gooseberries = 100% - (25% + 45%)

Now, let's calculate the percentage:

Percentage of land occupied by gooseberries = 100% - (25% + 45%) = 100% - 70% = 30%

Therefore, the percentage of the land occupied by gooseberries is 30%.

Angle Corresponding to the Land Occupied by Gooseberries

To determine the degree measure of the angle corresponding to the land occupied by gooseberries, we can use the fact that a full circle is 360 degrees. Since the percentage of land occupied by gooseberries is 30%, we can calculate the degree measure of the angle as follows:

Degree measure of the angle = 30% of 360 degrees

Now, let's calculate the degree measure:

Degree measure of the angle = 30% of 360 degrees = (30/100) * 360 degrees = 108 degrees

Therefore, the degree measure of the angle corresponding to the land occupied by gooseberries is 108 degrees.
