|dw:1435807242985:dw| The vertices correspond. a-x b-y c-z
then you can set angle b = y and solve for x
x = 8? I can't believe I did not see that. It looks so simple now that you've written it...
I've been there many a-time :p
Sorry x =16.
2x=32 x=16 yeah
ABC is congruent to XYZ. A = 50 B = 2x+40, Z = 4x + 8
you can make C = z then you know that all interior angle triangle angles add up to 180
|dw:1435807481419:dw| Like this?
But I don't have the value of "C"
c is z remember the congruence statement abc=xyz a=x b=y c=z
that doesn't seem right though
because I don't get an exact number for x
x = 12?
6*12 = 72 which leaves 10 remainder
check the angles to make sure they're right
or if you can give a fraction as an answer 41/3 is fine
Triangle ABC is similar to triangle XYZ. Side AB measures 2, side BC measures x + 5, side CA measures x + 7, side XY measures 4 and side ZX measures 4x – 2. Find the value of x. I'll give with it simplified and the fraction, that way I can't be wrong.
this is different. they're similar not congfruent
Is it a ratio thing?
looks good to me.simplify the leftside and then multiply both sides by x+5 to get rid of the deonominator on the right
or you could just "cross multiply" but that's unnecessary and not actually a technique technically
x = 5.5?
\(2(x+5)=4x-1\\2x+10=4x-1 \\11=2x\\x=5.5\) looks right
That doesn't work under my answers though, should be 6.33 7.2 5 8

looks like another careless mistake
Life hates me. x= 8
Triangle ABC is similar to triangle FGH. Angle A measures 42 degrees. Angle G measures 49 degrees. Find the measure of angle H.
similar polygons have equal angles
