Two angles of a triangle are the same size. The third angle is 12 degrees
smaller than the first angle. Find the
meone the ongles

Let the measure of the first angle be = x

Let the measure of the second angle = x

Then , the measure of the third angle = x - 12

Let us find the value of all of these angles using the angle sum property .

Sum of all angles inside a triangle = 180°

∴ The measure of the first angle = 64° , the measure of the second angle = 64° and the measure of the third angle = 52° .

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
