Question

Someone Help me i cant figure it out

Answer 1

Answer:

Below

Step-by-step explanation:

Because all the angles in a triangle add up to 180, we can set up an equation that looks something like this :

     (9x - 16) + (3x + 11) + (7x -5) = 180

Step 1. Group all the like-terms together :

     9x + 3x + 7x - 16 + 11 - 5 = 180

     19x - 10 = 180

     19x = 180 + 10

     19x = 190

Divide both sides by 19 to isolate x :

     x = 10

Hope this helps! Best of luck <3

Answer 2

Answer:

x=10

Step-by-step explanation:

all interior angles add up to 180

9x-16+3x+11+7x-5=180

19x-10=180

19x=190

x=190/19

x=10
