Answer:
a20 = -108
Step-by-step explanation:
53 - 62 = -9
44 - 53 = -9
35 - 44 = -9
Then the intervall is -9
The first number is 63
63 + (19*-9) = 63 - 171 = -108
Answer:
AE = 21.471cm long
(Rounded to 3 sig figs would be 21.5cm)
Step-by-step explanation:
Use the pythagorean theorem to find the length of AH
10^2 + AH^2 = 25^2
AH^2= (625 - 100)
AH = Square root of (525)
AH = 22.913
Plug in this value for AH to solve for AE using the pythagorean theorem
HE^2 + AE^2 = AH^2
8^2 + AE^2 = 22.913^2
AE^2 = 525 - 64
AE = Square root of (461)
AE = 21.4709
Hope this helps!
