Question 419652: The perimeter of an isosceles triangle is 35 cm. If the length of each of the congruent sides is 3 times the length of the third side, find the dimensions of the triangle.
So far I've got:
a + b + c = 35
3b = a
3b = c
I'm not sure if that's even right, though.
Thank you.

Question 420067: http://www.learningbygrace.org/geom/images/geom_11.2.gif
Complete the following proofs:
If two angles form a linear pair, then they are supplementary.
Statement 1: Ang ABD and Ang DBC form a Linear Pair. Reason: Given
Statement 2: Ang ABD + Ang DBC = Ang ABC. Reason: Definition of ____.
Statement 3: Ang ABC = ___. Reason: Definition of a Straight Angle
Statement 4: Ang ABD + Ang DBC = 180. Reason: _____.
Statement 5: Ang ABD and Ang DBC are supplementary. Reason: Definition of ____.
Not all choices will be used, and some choices may be used more than once.
a) Supplementary Angles
b) Linear Pair
c) Substitution
d)180
I know that statement 1 is given and statement 3 is 180 degrees, but I'm confused about the others. I think #2 is Linear pair, #4 is Supplementary Angles, and #5 is Linear Pair. Help me please.
