I just needed it to be explained on how to solve it. and congruent
ganeshie8 (ganeshie8):
good, when the triangles are congruent, the corresponding "angles" are congruent
ganeshie8 (ganeshie8):
\(6x = 30\)
solve \(x\)
OpenStudy (sbuck98):
5
ganeshie8 (ganeshie8):
Yep

Oh thanks! I thought it was a long process!!
ganeshie8 (ganeshie8):
you knew many things already.... so it is easy for you :)
ganeshie8 (ganeshie8):
#5 seems a bit confusing
ganeshie8 (ganeshie8):
lets try and make sense of whats going on..
OpenStudy (sbuck98):
I was confused on 5 I can solve simple ones like #5 but not the hard ones.

see if below makes sense for a)
congruent supplementary angles are right angles
ganeshie8 (ganeshie8):
b) definition of right triangle
ganeshie8 (ganeshie8):
c) Given.
ganeshie8 (ganeshie8):
see if that looks okay so far, they must be pretty straightforward
ganeshie8 (ganeshie8):
step d refers to a property of equality, see if you can figure it out

it does! would you help with a few more?
ganeshie8 (ganeshie8):
\(a = a\)
what property of equality is that ?
OpenStudy (sbuck98):
D is reflexive property of congruence right?
ganeshie8 (ganeshie8):
Excellent !
ganeshie8 (ganeshie8):
what about e
any guess ?

E is SSS?
ganeshie8 (ganeshie8):
Nope, we don't know all 3 sides in the triangles
ganeshie8 (ganeshie8):
use the fact that we have "right" triangles
ganeshie8 (ganeshie8):
what congruence theorems do you know that apply specifically to right triangles ?
OpenStudy (sbuck98):
definition of angle bisection

that is not a congruence theorem
OpenStudy (sbuck98):
:/
OpenStudy (sbuck98):
I don't know
