Let x be the time for the AG800. Then the time for the AG950 is x + 20.
Cross-multiplying and simplifying, we get:
The positive solution to this quadratic is: x = 15.
The answer is: Time for model AG800 = 15 minutes: time for model AG950 = 35 minutes.

Answer:
Step-by-step explanation:
We know by the Triangle Angle-Sum Theorem that the angles of a triangle all add up to equal 180. So we find angle B:
180 - 82 - 55 = 43
So angle B = 43. Now we can use the Law of Sines to solve for side b:
Cross multiply to get
b sin(55) = 8 sin(43) and divide to solve for b:
so
b = 6.6605
