➷ Angles on a straight line equal 180

Therefore:

10x - 20 + 6x + 8 = 180

Simplify:

16x - 12 = 180

Add 12 to both sides:

16x = 192

Divide both sides by 16:

x = 12

Answer:

x = 12

Step-by-step explanation:

Supplementary angles, sum = 180

10x - 20 + 6x + 8 = 180

16x - 12 = 180

16x = 192

   x = 12

Find the coordinates of point z such that the ratio of fz to zd is 5;3
Vilka [71]

The point such that the coordinate is 5;3 is (14, 0)

<h3>Midpoint of coordinates using ratio</h3>

The formula for finding the midpoint of a line in the ratio m:n is expressed as:

M(x, y) = {(mx₁+nx₂)/2, (my₁+ny₂)/2,}

Given the coordinate of G and D on the line as G(5, 0) and D(1,0)

Since there is no y-axis, hence;

x = 5(5)+1(3)/2

x = 25+3/2

x = 28/2

x =14

Hence the point such that the ratio is 5;3 is (14, 0)
