Answer:
Step-by-step explanation:
Use proportion- 63/42 as x/50
Use cross multiplication 63 times 50 = 42 times x
3150 = 42x
3150 divided by 42 = 75
The answer is: x= 75
Explanation:
As DY is parallel to FS which is DJ/FD = JY/SY.
50/x = 42/63.
1/x = 42/(50 × 63)
x = (50 × 63)/42
x = 3150/42
x = 75 units
