Answer:
Therefore the Length LY is 35 unit.
Explanation:
Given:
ΔTLY is Similar to ΔCHK
TL = 25
LY = 4x -1
CH = 10
HK = x + 5
To Find:
LY = ?
Solution:
Δ TLY ~ Δ CHK ........Given
If two triangles are similar then their sides are in proportion.
Substituting the values we get

Substituting 'x' in LY we get

Therefore the Length LY is 35 unit.
