Answer:
x=3y
Step-by-step explanation:
Step 1: flip the equation.
2x−5y=y
Step 2: Add 5y to both sides.
2x−5y+5y=y+5y
2x=6y
Step 3: Divide both sides by 2.
2x
2
=
6y

x=3y
Answer:
40 degrees.
Step-by-step explanation:
right triangle means an angle that is 90 degrees.
so the measure of the missing angle :
90+50+x = 180(for sum of all angles is 180 degree) (and we are assuming missing angle as x)
therefore x= 180-(90+50).
that is 180-140.
there fore missing angle measure is 40 defrees
