Step-by-step explanation:

2x + 15 + x + 90 = 180

3x + 105 = 180

3x = 75

x = 25

2(25) + 15 = 50 + 15 = 65 for m<D

the equation of the line that passes through the points $a(x_a,y_a)$ and $b(x_b,y_b)$ has o form

$\dfrac{x-x_a}{x_b-x_a}=\dfrac{y-y_a}{y_b-y_a}.$

if line passes through the points (-1, -3) and (2, 1), then

$\dfrac{)}{)}=\dfrac{)}{)},\\ \\\dfrac{x+1}{3}=\dfrac{y+3}{4},\\ \\4(x+1)=3(y+3),\\ \\4x+4=3y+3,\\ \\4x-3y+1=0.$

the equation in the standard form is

$4x-3y+1=0.$
