Set up:
6/(y - 4) - y/(y + 2) = (6/y - 4)(y/y + 2)
Take it from here. Solve for y.

4(5y-8-2) = 185-15
20y-32-8 = 170
20y-40 = 170
+40 +40
20y = 210
Divide both sides by 20
Y= 10.5
Answer: you need to add a picture, otherwise we don’t know how to help you answer that questions
Step-by-step explanation:
If the two triangles are congruent, you can just look at both triangles and see what is missing from each. They are all the same! :D
z = 10 yd
v = 7.9 yd
y = 38°
u = 6.2 yd
x = 90°
And to find w...
You know that the sum of all angles in every triangle is 180°. We know that two angles are 38° and 90°. Add them and subtract it from 180° to find the remaining angle.
90 + 38 = 128
180 - 128 = 52
So w = 52°
Hope this helps! :D
