Answer:
m∠ACB = 82°
Step-by-step explanation:
m∠ACB = 180° - m∠ACD
∠ACB and ∠ACD are supplementary, which add up to 180°
m∠ACB = 180° - 98°
m∠ACB = 82°

Answer:
6000
Step-by-step explanation:
so you have to divide 3000 and 6 to get 500
next you would do 500 times 6 equals = 3000
so now you would plus them and get 6000
now that is your answer

Answer:
Rate at which the shadow is moving = -5 ft/s.
Step-by-step explanation:
I can do the second part for you:
If the distance of the woman from the wall is Xp , the length of the shadow is Xs and the distance from the tip of the shadow to the wall is X we have the relation:
X = Xp + Xs.
We need to find X' (the rate that the tip of the shadow is moving). at Xp = 16 and X'p = -4 ft/s.
We need a relation between X and Xp so we have to eliminate Xs.
By similar triangles 5.5 / 27.5 = Xs / x
1/5 = Xs/x
Xs = x /5 so substituting in the above relation:
X = Xp + X/5
4X/5 = Xp
X = 5Xp / 4
Taking derivatives:
X' = 5X'p / 4
Now X'p is given as - 4 so
X' = -20/4 = -5 ft/s.
