The answer is 1/6 (one-sixth)
I’m not 100% sure but I think it’s D.
Because these triangles are congruent, then angle a is the same degree measure as angle x; angle b is the same as y; and angle c is the same as z. We also know that, because of the Triangle Angle-sum Theorem, all the angles of a triangle have to add up to equal 180 degrees. So for us that means that a+b+c(which is also z) = 180. 50 + 2x + 40 + 4x + 8 = 180. Combining like terms we have 6x + 98 = 180. Subbtracting 98 from both sides gives us 6x = 82 and x = 13 2/3
(x-2)^2 + (y-3)^2 = 25
center is 2,3
diameter is 10
rad is 10/2 = 5
Mark brainliest please
So first we add like terms inside the partenahseese
8-6x+12=-6x+8+12=-6x+20
now we have
1/4(-6x+20)
distribute
a(b+c)=ab+ac
1/4(-6x+20)=-6/4x+20/4=
-3/2x+5
-1 and 1/2x+5
