For this case we want to find this limit:
And using the properties of limit we got:
And replacing we got:
It would indicate that quartz and olivine have similar densities but olivine is a little more dense. It also indicates that gold has a much greater density than either of the others
2-(-x+5)
2+x-5
x-3

Answer: the measure of the remaining angle is 146 degrees
Step-by-step explanation:
The formula for finding the sum of the measure of the interior angles in a regular polygon is expressed as (n - 2) × 180.
A heptagon has 7 sides. This means that the sum of the angles in a heptagon is
180(7 - 2) = 180 × 5 = 900 degrees
Let x represent the measure of the remaining angle of the heptagon. If the measures of a heptagon are 127, 152, 112, 123, 135, and 105, it means that
127 + 152 + 112 + 123 + 135 + 105 + x = 900
754 + x = 900
x = 900 - 754
x = 146 degrees
