You have a right triangle (rhombus diagonals are perp.)
So add up all three angles and set them equal to...? (what is the sum of angles in a triangle)
OpenStudy (agent0smith):
The angles of the triangle are 90 (see above as to why), 2x+9 and 5x-3.
zarkam21 (zarkam21):
174/7
OpenStudy (agent0smith):
No, and show work.

solve for x right
OpenStudy (agent0smith):
Yes
zarkam21 (zarkam21):
Okay well you subtract 2x from both sides first
OpenStudy (agent0smith):
No, first write out the whole equation. I don't even know what you're working on.
zarkam21 (zarkam21):
2x+9+5x-3=180

zarkam21 (zarkam21):
Doesnt it add up to 180
OpenStudy (agent0smith):
"The angles of the triangle are 90, 2x+9 and 5x-3."
Add them up. Do not forget any. Set equal to 180.
zarkam21 (zarkam21):
So just do the equation as is 2x+9+5x-3=180
OpenStudy (agent0smith):
2x+9 and 5x-3 are only TWO of the angles in the triangle.

Exactly
zarkam21 (zarkam21):
Do we need more angles
zarkam21 (zarkam21):
Ugh so friggin confused
OpenStudy (agent0smith):
"The angles of the triangle are 90, 2x+9 and 5x-3."
zarkam21 (zarkam21):
Ohh so incorporate 90
