Find the cosine of ∠D.

Mathematics
1 answer:
Yuliya22 [10]2 years ago
5 0
It should be 5/13 because the opposite angle from D is 12, which you would use if you are looking for sine. But, since you are looking for cosine, it is adjacent over hypotenuse. Therefore leaving you with 5/13, since your hypotenuse is always your longest side and the adjacent is the other side from the one opposite of the angle.

8 x 4 = ( y x 7 ) - ( y x 3 )<br><br> What is y?
ASHA 777 [7]
8x4=32
32=(yx7)-(yx3)
(yx7)=7y
(yx3)=3y
32=7y-3y
7y and 3y are like terms so you subtract them
=4y
32=4y
then divided 4y by 4 (to get y on its own) this cancels out if you ÷ 4y on one side of the equation you have to divide on the other side to make it balanced 32÷4=8
y=8
