Answer:

x = 40

Step-by-step explanation:

x + 100 + x = 180 {Straight line angles}

2x + 100 = 180 {subtract 100 from both sides}

2x = 180 - 100

2x = 80 {Divide both sides by 2)

x = 80/2

x = 40

Please help me write an equation.

Answer:

k=6

Step-by-step explanation:

Line partition formula

1/b(x2-x1)+x1, 1/b(y2-y1)+y1

Where b is the number partitions.

We know the x values so Subsitue 17 for x2 and 2 for x1. and we know this value must equal 7.

1/b(17-2)+2=7

1/b(15)=5

1/b=1/3

b=3

so the partition is 1/3

$\frac{1}{3} (17 - 2) + 2 = 7$

So let find the y coordinate

$\frac{1}{3} (8 - 5) + 5 = 6$

So our y coordinate is 6.
