Let's say that the hypotenuse is length 1.
In a 45 45 90 triangle, the legs are equal to the hypotenuse * (1 / [sq rt (2)])
So if the hypotenuse =1, the legs equal 1 /

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)
Yes very good you are awesome but just to be confident about yourself check again<span />
