Answer:
x = 124°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5 , then
sum = 180° × 3 = 540°
sum the given angles and equate to 540°
90° + 122° + 105° + 99° x = 540° , that is
416° + x = 540° ( subtract 416° from both sides )
x = 124°
H= ut -16 t^2
h = 144(2) - 16 (4)
= 288 - 64 = 224
For this, we will be using dimensional analysis as such:

In short, 24,900 miles is 40,072,665.6 (40,072,666 if rounded to the whole meter) meters.
This is the answer that I came up with 12x^2-14x-6x+7 this is because the 2x and the 6x are multiplied together and then the 2x and the -7 are as well and the same is true of the -1 and the 6x and the -1 and the -7.
