A = 125

C = 35

Step-by-step explanation:

Since ABC is a triangle, all interior angles will add up to 180°. Therefore, A+B+C=180

Using that, u can substitute in the values of A, B, and C and solve for x:

A + B + C = 180

(6x - 1) + (20) + (x + 14) = 180

6x - 1 + 20 + x + 14 = 180

6x + x - 1 + 20 + 14 = 180

7x + 33 = 180

7x = 180 - 33

7x = 147

7x/7 = 247/7

x = 21

Knowing the value of x you can substitute that into the expressions for A and C, solve, and find their measure:

A = (6x - 1)

= 6(21) - 1

= 126 - 1

= 125

C = (x + 14)

= 21 + 14

= 35

u can check this by adding them all together and seeing if they add up to 180: 125 + 20 + 35 = 180, so that checks out.

hope this helps!

m∠A = 125°

               m∠C = 35°

Step-by-step explanation:

(6x - 1) + 20 + (x + 14) = 180

6x - 1 + 20 + x + 14 = 180

7x + 33 = 180

7x + 33 - 33 = 180 - 33

7x = 147°

7x ÷ 7 = 147 ÷ 7

x = 21

m∠A = (6 · 21 - 1)° = 125°

m∠C = (21 + 14)° = 35°

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
