Here, You have to simplify every number to their simple form and place it on the arrow by approximation:
So, Here is your answers:
Upper Arrows (From Left towards right):
1st = -10√2/3
2nd = -√7
3rd = ∛4
4th = √50
Lower Arrows (From Left towards right):
1st = -√99
2nd = -√17
3rd = ∛9
4th = π
Hope this helps!
Answer:
∅ = 42°
Step-by-step explanation:
90 - 48 = 42° because 48 and 42 are complimentary angles (add up to 90°)
because the radii lines form an isosceles triangle, ∠∅ also = 42°
Usually first comes x the horizontal
then y the vertical
so the vertical distance is 8
Combined work problems
job/time + job/time = job/ total time
(1/80) + (1/100) = 1/T
(10/800) + (8/800) = 1/T
18/800 = 1/T
800/18 = T
44.44 hrs = T
