|dw:1327972990128:dw| find the range of values for z
can u please redraw the figure??
|dw:1327973646692:dw| there?..please help?
that 4z-12 is an angle?
that's how it's drawn in my book..more like this..|dw:1327974111848:dw|
but it's same thing right?
well monster, can u tell if these triangles are right angle?
none of them are?
that's really funny, are you sure u have put every information?
i forgot the 16 on the first triangle..
so sorry, but i have no idea right now, hope that any other member can help, i'd like to see the solution
I see three unknowns, z, a (the shorter length) and b (the longer length). I find only two equations, namely by the cosine rule of each triangle. Also, z appears in only one place, so that's "fishy". Can you dig out some more information from the question? For example, copy the question verbatim?
Omar- Thank's Anyways Math Mate- i don't know that's all it says on my book..
65 degrees is opposite to side with length 16 54 degrees is opposite to side with length 4z-19 we know that side opposite to larger angle is larger than the side opposite to smaller angle, so 65>54 16>4z-19 25>4z 25/4>z or z<25/4
Good job! I didn't even read the question line. Grrr.
That just clicked..thank you ash2326 (:
