first, find the numeric value for 11/15
second to find theta, simply do the <em>inverse</em> cos (which is cos^-1) of the first answer.
now you know theta, just do the sin of 90 - theta and that's it!
since you know whatr cos(theta) is, you just take the inverse cos of that number to get theta and 'reverse' cos, essentially. you are just solving for theta, by reversing the cos function with cos^-1
please mark as brainliest!
So its 45 for every visit so your x is the amount of visitsso 45x plus 25 each hour you could represent with a h so 25h
The question is asking you to write and solve an equation that includes 2 different sites (45*2) and how many hours itd take to achive 810 so 810 would be on the other side of your eqaul sign
180 cubic units
Explanation:
To find the volume of a rectangular prism, multiply together length • width• height.
Height- 5
Width- 9
Length- 4
5 x 9 x 4= 180
Com.ment me if my answer is correct.
MARK ME BRAINLIEST TYSM! Have a nice day/night!
Alright, lets get started.
We could use sine law to find the remaining angle.


Plugging the value of sin 64


Cross multiplying
sin S = 0.8189
Taking inverse on both side

S = 55° : Answer
Hope it will help :)
