Answer:
The water level will change at a rate of - 2 7/18 inches per year
Step-by-step explanation:
From the question, we have a change of -7 1/6 inch every 3 years
We now want to calculate the value of the change every year
Mathematically, that will be;
- 7 1/6 divided by 3
= -43/6 divided by 3
= -43/18 = - 2 7/18 inch per year
Answer: yes
Step-by-step explanation:
Answer:
72
Step-by-step explanation:
The area of a polygon is sidelength * apothem * # of sides* (1/2)
That means the area is: 6 * 4 * 6 * (1/2) = 72
If a line is drawn across the shape connecting two of the angles it makes two triangles. The sum of the angles in a triangle is 180 degrees.
Since this shape makes two triangles the sum of the inside angles is 2 * 180 = 360 degrees
(2x - 17) + 90 + x + 59 = 360
combine like terms
3x + 132 = 360
3x = 360 - 132
3x = 228
x = 76
Answer:
70°
Step-by-step explanation:
All triangles' angles are added up to 180°
30 + 80 + x = 180
110 + x = 180
x = 180 - 110
x = 70
