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: It's 35.5 and 38.5
Step-by-step explanation:
First, subtract 74 by 3 giving you 71.
Next, divide 71 by 2; it gives you 35.5 (that's your first number).
Then, add the 3 that you took away to 35.5 and get 38.5 (that's your second number).
A;
[(4 x 6) + (5 x 2)] - [(14 x 2) + 7]
B;
[(4 x 6) + (5 x 2)] - [(14 x 2) + 7]
[24 + 10] - [28 + 7]
34- 21
