Rewriting the equation of the given line in slope-intercept form,

Thus, the slope of the given line is 2/3. Since perpendicular lines have slopes that are negative reciprocals of each other, we want to find the line with a slope of -3/2.
Substituting into point-slope form,

(4x - 2)* 6(2x + 7)
=(4x - 2)(12x + 42)
= 4x(12x + 42) - 2(12x + 42
= 48x^2 + 168x - 24x - 84
= 48x^2 + 144x - 84 Answer
An acute angle is <90 degrees
a right angle is equal to 90 degrees
an obtuse angle is >90 degrees
Any triangle has angles adding to 180 degrees
therefore three acute angles, eg. 60, 60 and 60 degrees can make up a triangle
2 acute angles and a right angle, say 45 and 45 degrees and 90 degrees make a triangle
any obtuse angle + a right angle will be larger than 180 degrees, so no triangle can exist. another acute angle will make the number of degrees even larger
any 2 obtuse angles will make a number larger than 180 degrees, so with an acute angle is impossible
2 acute and an obtuse angle is possible, say 40, 40 and 100 degrees
