Answer:
<h2>m∠ABD = 20°</h2>
Step-by-step explanation:
If m∠ABC = 40° and BD is the bisector of ∠ABC, then
(1) m∠ABD = m∠DBC
(2) m∠ABC = m∠ABD + m∠DBC
From (1) and (2) we have:
m∠ABC = 2m∠ABD
Therefore
2m∠ABD = 40° <em>divide both sides by 2</em>
m∠ABD = 20°
Answer:
y= 9
Step-by-step explanation:
4y-y+11=38
3y+11=38
3y= 38-11
3y= 27
y= 27/3
y=9

Answer:
42y-48
Step-by-step explanation:
6 x 7
6 x 8
We want to get x by itself so we combine like terms first.
First subtract 4 from both sides
4+11x=9x+2x
Now add 9x and 2x together
4+11x=11x
Subtract 11 from both sides
4=0
The equation is false.
