Answer:
[tex]7(14)-11=87\\\\5(14)-2=68\\\\2(14)-3=25[/tex]
Step-by-step explanation:
First we need to set up an equation in order to find the value of x. We know that the sum of these angles are 180°
[tex]7x-11+5x-2+2x-3=180\\\\14x-16=180\\\\14x=196\\\\x=14[/tex]
Now we can plug in our value for x into each of the angle's equations
[tex]7(14)-11=87\\\\5(14)-2=68\\\\2(14)-3=25[/tex]
