For the figure shown on the right, find the value of the variable and the measures of the angles

x=38

Step-by-step explanation:

the angles of any triangle always equals 180

so to find x we set up an equation like this: (2x+8)+(2x-18)+X=180

calculate to find x

Combine like terms: (2x+2x+x)+(8+−18)=180

2x+2x+x=5x

8+(-18)=-10

now we have 5x+(-10)=180

Add 10 to 180, then divide 190 by 5.

180+10=190/5=38

x=38

to find the measures put 34 into the angle equations

2(38)-8=58

2(38)+18=84

x=38

the graph on the bottom right

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
