9. Given cot(a)= 6/5 and cos(B)= 4/7 for a third-quadrant angle (a) and a fourth-quadrant angle (B), use the Definition of Trigonometrie Functions of Any Angle to find the exact value for cos((a)+(B)). Show the formula you are using in your work. Notice that the "SOHCAHTOA" method does not apply here. The angles (a) and (B) are not acute angles inside of a right triangle. Apply the Definition of Trigonometrio Functions of Any Angle.

answer: i could not see part the question so ill explain how to get the answer

step-by-step explanation: for instance the distance she travele d is 10 and she traveled the same amout each mile so do 10 divided by how many miles she drove each time and you ge your answer.

hi,

the area of abcd is 245.

3*24=230

4*94=1039

2*12=24

add all of them up, you get 2450

1. she sold more on day 2 because if you turn .85 into a fraction{85/100} and you give 7/9 and 85/100 the same denominator{180} you can see which one has the bigger numerator and that one will be the most sold.

2. yes it is in simplest form, because if you look at 38 and 53 's greatest common factor, you cant find one so you cant reduce it

3. no, this is not a prime factorization because the numbers are not all prime numbers, the correct prime factorization is:   2 x 5 x 2

4.   in 12 days he will run and play trumpet again

work 4 4: 123123123123

                123412341234     in 12 days he will play the trumpet and run on the same day

step-by-step explanation:

i am normally pretty good at math, im new to this site, but im 1 grade ahead in my math, i luv math try my answers out, see how they work
