What is the value of x? enter your answer in the box. x = an equilateral triangle r t s with vertical base r t and vertex s is right of the base. side r t and t s and s r are labeled with single tick mark. angle r s t is labeled as left parenthesis 7 x plus 4 right parenthesis degrees. angle r t s is labeled as left parenthesis 8 y plus 12 right parenthesis degrees.

 x = 8

Step-by-step explanation:

Since, RTS is the equilateral triangle.

Thus, RT= TS = SR

And, ( By the property of the equilateral triangle.)

Here, Given  ∠ RST =  (7 x + 4)°

And, ∠ RTS = (8y +12)°

Therefore, (7 x + 4)° = 60°

⇒ 7 x = 56

⇒ x = 8

x=8

Step-by-step explanation:

Since, RTS is the equilateral triangle.

Thus, RT= TS = SR

And,  ( By the property of the equilateral triangle.)

Here, Given  ∠ RST =  (7 x + 4)°

And, ∠ RTS = (8y +12)°

Therefore, (7 x + 4)° = 60°

7 x = 56

x = 8
