Greetings!

Answer:

x = 8°

Explanation:

Because this triangle is an equilateral triangle, as indicated by the lines which say all lines are congruent, it means every angle, R S and T, are exactly the same amount. 60°

This means that angle S = 60 so:

7x +4 = 60

Simply move the 4 over to the other side, making it a negative:

7x = 60 - 4

7x = 56

So now simply divide both sides by 7:


(7x)/(7) = (56)/(7)

x = 8

So the value of x is 8°!


Hope this helps!
