Congruent is the same size and same shape. When a ray bisects an angle, the two newly created angles will be congruent, since the ray went right in the middle of the first angle (so in this case, ABC and DBC will be congruent)
I think the answer is 210.442
Step-by-step explanation:
multipy the two sides by 2
n+4= -16
move the constant to the right change its sign
n= -16 - 4
calculate the difference
N= - 20
Answer:
yes
Step-by-step explanation:
1x+3y=8
3x+2y=10
solve
multiply first equation by -3 and add to 2nd equation
-3x-9y=-24
<u>3x+2y=10 +</u>
0x-7y=-14
-7y=-14
divide by -7 both sides
y=2
sub back
x+3y=8
x+3(2)=8
x+6=8
minus 6
x=2
