The general form for a straight line is y = mx + c where m is slope and c is y-intercept.
Two lines are perpendicular when the product of their slopes = -1
Given line 3x - 7y - 14 = 0, its slope = 3/7 and y-intercept = -14/7 = -2
So a line perpendicular to the given and has the same y-intercept is
y = (-7/3) x - 2
Answer:
505.4 in²
Step-by-step explanation:
½d2= 19×tan 35° = 19×0.7 = 13.3 in
d2 = 2×13.3 = 26.6 in
d1 = 2×19=38 in
the area of Rhombus =
½×38×26.6 = 505.4 in²
