The element X is titanium.

According to the question, the percentage by mass of Cl in XCl4  is 75.0%.

The percentage by mass is obtained from;

Mass of element in the compound/molar mass of compound * 100

Hence;

Let the mass of the unknown element be X

75 = 142/X + 142 * 100

75 (X + 142) = 142 * 100

75X + 10650 = 14200

75X =  14200 - 10650

X = 14200 - 10650/75

X = 47

Hence, X is titanium.
