The solution would be like this for this specific problem:

sin 54 degrees = Height/718.0624

Height = (sin 54 degrees)(718.0624) = 580.9 ft

So the height of the balloon is 580.9 ft. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Answer:

$The~sum~of~angles~shown~in~the~figure~gives~a~complete~turn.\\Therefore, (2x+16)^o+35^o+(4x+3)^o = 360^o\\or, 6x+54^o = 360^o\\or, 6x = 306^o\\or, x = 51^o$

jim and lisa had a total of $300. After jim boughy a jacket with 2/3 if her money,she had $90 less than lisa. find the cost of t

Yuri [45]

Answer:

$84

Firstly, what we must do, is establish a system of equations:

$\frac{2}{3}J = L -90$

$J + L = 300$

Due the circumstances, it is decided we will use the method of substitution:

$\frac{2}{3}J = L - 90$

$\frac{2}{3}J + 90 = L$

↓

$J + \frac{2}{3}J + 90 = 300$

Now, we solve the 2-variable equation above:

$J + \frac{2}{3}J + 90 = 300$

$J + \frac{2}{3}J = 300 - 90$

$J + \frac{2}{3}J = 210$

$J(3) + (\frac{2}{3}J)(3) = 210(3)$

$3J + 2J = 630$

$5J = 630$

$J = \frac{630}{5}$

$\bf~J = 126$

Now, we must see how much money each one of them had & the price of the jacket:

Now we know that Jim had $126. In other words, $126 is $\frac{3}{3}$ of his money (total money).

So, if Jim has $126, which corresponds to $\frac{3}{3}$ of his money, $\frac{2}{3}$ of his money is:

$\frac{126}{3} = 42$

$126 * \frac{2}{3} = 42 + 42$

$\bf~126 * \frac{2}{3} = 84$

Hope it helped,

the points (4,-4) and (4,-6) lie on a circle with the radius of 1. what is the center point of the circle

ycow [4]

The centre point is given by;
$( \frac{ x_{2}+ x_{1} }{2} , \frac{ y_{2} + x_{1} }{2} )$
= $( \frac{4+4)}{2} + \frac{-4+(-6)}{2} )$
= $( \frac{8}{2} , \frac{-10}{2} )$
=(4, -5)
