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.
The answer is C. A square root is two numbers multiplied by itself. The square root of 44 is 6.63. When you multiply 6.63 by itself you get 44. Hope this helps!
Answer:
Step-by-step explanation:
To divide a fraction by a number just reciprocate the number which is there after division sign as done here. If there is one more fraction then reciprocate the fraction.
∴
(NOTE : <em>Reciprocating means interchanging the numerator and denominator of that fraction</em>.)
16 rounded to the tens place = 20
6216 rounded to the thousands place = 6000
6000/20 = 300 <==
Linear decreasing because it is a line with a negative slope
