6x + y = x + 5y
5x = 4y
4x + 6x + y = 180
10x + y = 180 so y = 180 - 10x
substitute y = 180 - 10x into 5x = 4y
5x = 4y
5x = 4(180 - 10x )
5x = 720 - 40x
45x = 720
x = 16
answer A.
x = 16
Answer:
ΔRHS ≅ ΔNKW
Step-by-step explanation:
We are given that, in the triangles RHS and NKW.
∠H = ∠K
Side HS = KW.
∠S = ∠W
Now, using the ASA congruence criteria, which states that when two corresponding angles of the triangles are equal with the included side between them is equal, then both the triangles are congruent.
Hence, according to ASA criteria, ΔRHS ≅ ΔNKW.
