I cannot follow your description. Since DB and DC are parallel, D is on both lines, and BDC must be a straight line. So how does DA intersect BC ???

Geometry
well, what's the problem? A vertical line through P will have x=3. Cmon, guy, put on your thinking cap!
Monday, October 14, 2013 at 4:08am

Geometry
This is a horizontal line, so a perpendicular line gives you a constant x value, providing the equation x=3

Write an equation of the line that pass through point P and is perpendicular to the line with the given equation. P(3,5); y=4

Geometry
The actual question is : Write an equation of the line that pass through point P and is perpendicular to the line with the given equation. P(3,5); y=4
Monday, October 14, 2013 at 12:51am

Geometry
Sorry, I meant to say perpendicular instead of parallel.
Monday, October 14, 2013 at 12:23am

Geometry
since y=4 is a horizontal line, you want a horizontal line that passes through P, where y=5. Oops Spoiler alert!!

not enough information. Are AC and BD on the same straight line? Are AC and BD parallel lines? I drew AC and BD as two non-parallel distinct lines and the problem made no sense

But is 5a equal to 5b?
Wednesday, October 2, 2013 at 7:55pm

Geometry
correct. But your reasoning is skewed. Forget about some "b". Substitute 20 for a. 5a = 5(20) = 100
Wednesday, October 2, 2013 at 7:51pm

Geometry
Substitution Property of Equality: If a=20, then 5a= _____. The substitution rule states that If a=b then a can be substituted for b in any equation or expression. So I think that 5a=5b but the number answer is 100. Am I correct?

Note that point B is in segment AC, therefore we can say that the sum of lengths of AB and BC is equal to AC, or AB + BC = AC Substituting, (2x - 1) + (3x + 5) = 24 5x + 4 = 24 5x = 20 x = 4 Thus, AB: 2(4) - 1 = 7 units Hope this helps~ :3

In the example I gave you, the altitude will not reach the base. Notice I took the smaller side as my radius and the arc cannot reach the base. height/10 = sin30 height = 10sin 30 = 5 so my second side would have to be at least 5 by taking the longer of the 2 given sides, you ...

You posted this earlier, and it still makes no sense, as Steve pointed out in that post. Are you talking about "construction" as with ruler and compass in geometry. Are you perhaps trying to construct a triangle ABC, where AB = 10, AC = 4 and angle B = 30°
