A triangle’s angles will add to 180
(2x-33)+(2x+15)+2x=180

Add like terms
6x-18=180

Isolate the X
6x =198
x=33

Check answer
2(33)= 66
2(33)+15= 81
2(33)-33 =33
66+81+33=180
x=33

Find the equation of line passing through points A (1, 3) and B (3, 7).

Sidana [21]

Solution:

To find the equation of line passing through points A (1, 3) and B (3, 7).

we know that, to derive the equation of a line we first need to calculate the slope of the line. Slope m of a line at points $(x_{1} ,y_{1})$ and $(x_{2}, y_{2})$ is given by - $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .
