Your answer would be C.
If you substitute 14 for X and add it to 9. You would get 23
Given that the <em>length</em> ratio between the radii of the two circles is (2 · x) / (5 · y). The ratio of the areas of the two circles is (4 · x²) / (25 · y²).
<h3>What is the area ratio of two circles?</h3>
According to the statement we know that the radius ratio between two circles. Given that the area of the circle is directly proportional to the square of its radius, then the <em>area</em> ratio is shown below:
A ∝ r²
A = k · r²
A' · r² = A · r'²
A' / A = r'² / r²
A' / A = (r' / r)²
A' / A = [(2 · x) / (5 · y)]²
A' / A = (4 · x²) / (25 · y²)

Answer:
151°
Step-by-step explanation:
Pentagons interior angles are always 540°. So to solve, you must put
540= (5x+2)+(10x-3)+(8x-19)+(7x-11)+(13x-31). After solving this you will get x=14 and you can now substitute x in for measure s.
13(14) -31
182 - 31
measure of s = 151°
you would cross multiply meaning 6(2x+2)=11(x-4) Then you distribute 6 so it would be 12x+12=11x-44 then you have to move the constant and the variable so 12x-11x= -44-12 so then the answer would be x = -56
