A proportion is two ratios equivalent to each other
To find the perpendicular line a y- 2 = 7/3 (x + 5) you must first observe that the slope is m = 7/3, therefore, the slope of the perpendicular line put of the reciprocal, that is, m = - 3/7. So the possible options are A or C, but since the point (-4, 9) must go through the line, we find that the equation that satisfies that is option C.Therefore the perpendicular line that passes through the point (-4, 9) is C. y - 9 = -3/7 (x + 4)
In the given figure, Angle 23x and Angle 24x - 5 are equal because they form pair of Alternate Interior Angles.
So,
value of x = 5,
now, measure of each angle = 23x = 23 × 5 = 115°
