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

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this
