**Step-by-step explanation:**

0.45 kilograms. you decide the mass value by 1000.

**Step-by-step explanation:**

Here we can see it is a quadrilateral so

**x ****+**** ****1****0****8****°**** ****+**** ****6****5****°**** ****+**** ****5****3****°**** ****=**** ****3****6****0****°**** ****(**** ****being ****sum ****of ****angles ****of ****quadrilateral****) **

**2****2****6****°**** ****+**** ****x ****=****3****6****0****°**

**x ****=**** ****3****6****0****°**** ****-**** ****2****2****6****°**

**Therefore ****x ****=**** ****1****3****4****°**

First notice that the triangle with sides

and the triangle with sides

are similar. This is true because the angle between sides

in the smaller triangle is clearly

, while the angle between sides

in the larger triangle is clearly

. So the triangles are similar with sides

corresponding to

, respectively.

Now both triangles are

, which means there's a convenient ratio between its sides. If the length of the shortest leg is

, then the length of the longer leg is

and the hypotenuse has length

.

Since

is the shortest leg in the larger triangle, it follows that

, so

8,8,6,9,8,3,12,9,3,12,5,0,4,8,5,9,5,8 these are the answers in a series

The answer will be 4 weeks. You know the constant is 1.5 lbs per week and you will multiply that by however many weeks it takes to reach 176

197-(1.5x) would be your equation and since he’s already lost 15 pounds you will include that by subtracting 15 from the equation as well 197-(1.5(4))=191

191-15=176
