Question

Help please... I really didn’t understand this lesson.

Answer 1

7(14)-11=87

2(14)-3=25

5(14)-2=68

Explanation:

Ight Homie, lemme help you out.

To start, add (7x-11) + (2x-3) + (5x-2)

That should get you (14x-16)

Then set up the equation

14x-16=180

180 is the sum of the triangle angles. (if i said that right)

Then solve for x

14x-16=180

+16 +16

14x=196 Divide

((14x)/14)=196/14

x should equal 14.

Then replace x with 14

7(14)-11=87

2(14)-3=25

5(14)-2=68

I hope this helps. Stay safe Homie!
