Question

Triangle RSV is congruent to triangle TVS. Find y

Answer 1

Triangle RSV is congruent to triangle TVS.

So,

|RS|=|TV|

|SV|=|VS|

|VR|=|ST| (They are hypotenuses of the congruent triangles).

|VR|=25

|ST|=4y-2

25 = 4y - 2

4y=27

y=27/4=6.75

y=6.75

Answer 2

ΔRSV ≡ ΔTVS

⇒ Line ST ≡ Line RV

.

Solve y:

4y - 2 = 25

4y = 27

y = 6.75

.

Answer: y = 6.75
