Step 1: Find X

3x + 7 + 9x + 17

Add the alike terms: 12x + 24

Linear is 180 degree, 12x + 24 = 180; now find x

X = 13

Now find the degree for both.

RST: 3 (13) + 7 = 46

VST: 9 (13) + 17 = 134

You're answer is A

The correct option is A

would you like an explanation?

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
