D = 25 ft is the length of a shadow. L - the length of a tree.
Two angles are 85° and 65° and the third is 180° - ( 65° + 85° ) =
= 180° - 150° = 30°.
We will use the Sine Law:
25 / sin 30° = L / sin 65°
25 / 0.5 = L / 0.9063
25 * 0.9063 = 0.5 L
22.6577 = 0.5 L
L = 22.6577 : 0.5
L = 45.3 ft.
Answer: the approximate length of the tree is 45.3 ft.
Answer:
-4
Step-by-step explanation:
('+')('-') = ('-')
Therefore,
(+2)(-2) = (-4)
Answer:
B of course you dummy
Step-by-step explanation:
Multiplying 20 by 320% is the same thing as multiplying 20 by 3.2, or 20(3.2)=64. Hope this helped!
Cindy used 17.25 because 15 × .5 = 2.25 and if you add it to 15 ypu get 17.25
