Answer:

x = 8

Explanation:

See the diagram first which is attached.

We see from the diagram that Δ RST is an equilateral triangle having equal length of its sides i.e. RS = ST = TR

Hence, the angles of the triangle will also be the same and equal to 60°.

Now, ∠ S = 60 = 7x +4 {Given}

⇒ 7x = 56

x = 8 (Answer)
