Well, in order to answer this problem we need to use the <span>the Pythagorean Theorem and the it will be like this:
cos = x / hypotenuse
cos= 12/13
I think with this you can figure the rest out. Hope this helps</span>
Answer:
one solution
d=-2
Step-by-step explanation:
4(3d - 7) = -52
There is one solution to this equation
Distribute
12d -28 = -52
Add 28 to each side
12d-28+28 = -52+28
12d =-24
Divide each side by 12
12d/12 = -24/12
d = -2
2y=x-2
I'm learning this now so ik it's right
