The triangles ΔDJY and ΔFJS are similar triangles. Then the value of x will be 75. Then the correct option is D.
What is the triangle?
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The angle ∠J is common for both triangles.
The triangles ΔDJY and ΔFJS are similar triangles, then we have
DJ/DF = YJ/YS
50/x = 42/63
x = 75
