Answer:
if i am rightthe two other angles arre 39
Step-by-step explanation:
if a triganle is 180 degrees and you have already one angle then all you do is subtract 180 and 102
180-102= 78
then since you need the other two angles all you do is divide it by 2
so 78/2= 39 so the two missing anlges are 39
Answer:
25 + x = y
Step-by-step explanation:
He gets x(unknown amount of cards) so add that, and the total will equal y.

Answer:
2x(x-3)(-x+1)
Step-by-step explanation:
Factor 2x from everything -> 2x(4x-3-x^2)
Reorder the terms -> 2x(-x^2+4x-3)
Write 4x as a sum -> 2x(-x^2+3x+x-3)
Factor out -x from -x^2+3x looks like -> 2x(-x(x-3)+x-3)
Factor out x-3 from the expression -> 2x(x-3)(-x+1)
