Answer:
a.) (x-3)(x-3) = 25 + (x-4)(x-4)
x^2 - 6x + 9 = 25 + x^2 - 8x + 16
-6x + 9 = -8x + 41
2x + 9 = 41
2x = 32
x = 16
b.) 16 - 4 = 12
AB = 12
c.) 16 - 3 = 13
AC = 13
[btw I don't know if this is the method your teacher wants as it does not use the similar triangle :/ but it is still correct :) so good luck bro]
Answer:
x= -2
y= 0
Step-by-step explanation:
Or (-2,0)
Answer:
x=2
SK=21
KY=13
SY=34
Step-by-step explanation:
finding x:
SK+KY=SY
13x-5+2x+9=36-x
get x by itself
13x+2x+1x=36+5-9
simplify
16x=32
divide by 16 on both sides
x=2
Now plug in x (2) into the separate formulas
SK:
13(2)-5
26-5
21
KY:
2(2)+9
4+9
13
SY:
36-(2)
34
To double check your answer plug in what you got
SK+KY=SY
21+13=SY
34
and we got 34 above so this is correct.
