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!
Answer:
Step-by-step explanation:
<u>Perimeter is:</u>
- P = a + b + c
- P = 4x - 3 + x + 9 + 8 = 5x + 14
<u>Area is:</u>
- A = 1/2bh
- A = 1/2*8*3x = 12x
Correct choice is A
Answer: A
(He has the side lengths in the wrong place in the cosine ratio)
Answer:
58/9
Step-by-step explanation:
5/3 +43/9
Lets take the L.C.M first
The L.C.M would be 9
Solve the term by taking 9 as L.C.M
=15+43/9
Add the numerator.
=58/9
The answer is 58/9 ....
Since there is no base down payment or anything the equation i think would just be 35m = c
If there was say a one time payment of $20 and then the monthly payments it would look like 20+35m=C
I hope this helps :)
