Answer:
Step-by-step explanation:
Given:
Angle of elevation = 70°
Length of string = 68 m
We need to find the height of the kite.
Solution:
Requirement figure attached in file.
Where:
BC = 68 m
AC = h (Height of the kite)
∠ABC = 70°
Using Cosine rule to find the height of the kite.
Therefore, height of the kite from Brian's head .
means to say there is some
such that
. Similarly,
is equivalent to saying there exists
![k_2[/te]x such that [tex]n=dk_2](https://tex.z-dn.net/?f=k_2%5B%2Fte%5Dx%20such%20that%20%5Btex%5Dn%3Ddk_2)
.
Now,
, i.e. there is some
such that
is a multiple of
, i.e.
.
Answer:
Step-by-step explanation:
m= month
3÷100= 0.03
0.03×500=<u>$15</u>
$15/m
$15×5×12=$900
$500-$900= <u> </u>
<u>Answer: -$400</u>
5 × (x + 12) = 80
5x + 60 = 80
5x = 20
x= 4
