Answer:
b.y=4
c. x=6
These are the answers hope this helps
(b+c)(x+3)
I hope this is true
1st disribute .4 through the parentheses.
.4 (.3x-1)=2+.75x
.12x-.4=2+.75x
subtract .12x from each side
-.4 = 2 + .63x
subtract 2 from each side
-2.4 = .63x
Divide each side by .63
-3.81 = x
All the angles in a triangle= 180 degrees.
2x+5x+3x= 180
Combine like terms.
10x= 180
Divide by 10 into both sides.
x= 18
Now, plug that into <L.
3(18)= <L
<L= 54 degrees
I hope this helps!
