Help plz I have 6 minutes

x = 105

Step-by-step explanation:

Sum of n-sided polygon = (n - 2)*180

The polygon given is a 7-sided polygon, therefore substitute n = 7 into (n - 2)*180

Sum of the polygon = (7 - 2)*180 = 900°

Thus:

x + 102 + 165 + 123 + x + 11 + 128 + 161 = 900

Add like terms

2x + 690 = 900

2x = 900 - 690

2x = 210

x = 210/2

x = 105

at home andrea has 1 2/3 kilograms of rice

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
