Question

Find RT if RT=x-6and the measure of angle PTR is 8x-6

Answer 1

What chapter is this in Geometry or what section?

Answer 2

I don't know because this is a review problem... I took geometry years ago... but the worksheet is titled Bisectors, Medians, and Altitudes

Answer 3

Any thoughts?

Answer 4

No, I'm trying to think though.

Answer 5

OK

Answer 6

I think I got it...

Answer 7

PTR is a right triangle... this is dealing with altitudes. We know this is a right triangle because PT is the altitude.

Answer 8

PTR = 90

Answer 9

Oh...I think I get it now, thank you so much!

Answer 10

8x - 6 = 90

Answer 11

8x-6=90
+6 +6
-----------
8x = 96
x = 12

Answer 12

RT = x-6
12-6

RT = 6

Answer 13

OK thanks!
