Question

What is the value of x? x = ___

Answer 1

Greetings!

Answer:

x = 8°

Step-by-step 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:

$\frac{7x}{7} = \frac{56}{7}$

x = 8

So the value of x is 8°!

Hope this helps!
