Here,
y=mx+c
the slope of the line 6x+4y= -16 is -20.
if the two lines are perpendicular, the slope of 1st line * slope of second line=-1
the slope of the 2nd line is -1/2
y-y1=m(x-x1)
y-13=-1/2(x- -18)
when you solve, you get the equation of the line as 2y+x=50
In basic geometry, if two geometry objects intersect at right angles (90 degrees or π / 2 radians), they are vertical.
If two lines intersect at right angles, the line is perpendicular to another line. Explicitly (1) if two lines intersect, the first line is perpendicular to the second line. (2) At the intersection, the straight line angle on one side of the first line is cut by the second line into two congruent angles. Verticality can be shown as symmetric. That is, if the first line is perpendicular to the second line, then the second line is also perpendicular to the first line. Therefore, two straight lines can be said to be perpendicular (to each other) without specifying the order.

Answer: <DEF & <JKL
Step-by-step explanation:
they equal 90 degrees
complementary angles equal 90 degrees
I am pretty sure your answer is going to be <span>58.8, I hope this helps!! :)</span>
let the length of side number one and two be x
length of side number three = 2x-1
x + x + 2x - 1 = 31
4x=32
x=8
2x-1= 15
length of third side = 15cm
C because if you look at it 1 1/4 it passes 2 1/4 so you know it’s gonna be 1 something and 2 1/2 is one after 2 1/4 so to get to 3 1/4 that would be 3 so 1 1/4 is the answer... if that make sense if not I can write it out to you and send a picture of how it’s worked out
