Answer:</h2>
D. Inscribed angle
<h2>
Step-by-step explanation:</h2>
An inscribed angle has a vertex on the circumference. For any arc, every inscribed angle is exactly half of the central angle. In other words, if the central angle is 
and the inscribed angles is 
, then it is true that:
In this problem 
, then the central angle is 
1) a
2) c
#1 explanation:
x^4-20x^2=-64
x^4-20x^2+64=0
(find a number that multiplies to the last number aka 64 and adds up to b aka 20)
((x-4)(x-16))^2
x= -2,2,-4,4
same for #2 w different variable and numbers
To find the unit rate, we need to divide 6 by 51.
51/6 = 8.50

G(x)=X+11 where y is the total temperature after it rose & x is the temperature when Iko woke up. F(x)= g(x) -14 . Where f(x) is the temperature after it dropped 14 and g(x) is the temperature it was by lunch time.
5x=3x+20
5x-3x=3x-3x+20
2x=20
2x/2=20/2
X=10 Hope this helped!
