Would do 4 much more pts. this ones a toughie!
Answer:
y =52
Step-by-step explanation:
We know that the angles 4x and 5x make a straight line
4x+5x = 180
9x = 180
Divide by 9
9x/9 = 180/9
x = 20
The three angles of a triangle make 180
y + 48 +4x = 180
y + 48+4(20) =180
y + 48 +80 = 180
Combine like terms
y +128 = 180
Subtract 128 from each side
y + 128-128 = 180-128
y =52
If AB and BC are equal then AC should be 29
How did I get this?
x+4=2x-10
14=x
Plug it in
AC= 2(14)+1
AC=28+1
AC=29
KEEP IN MIND THIS WILL MOSTLY LIKELY ONLY WORK IF IT SAYS AB AND BC ARE EQUAL
