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 = -5/8
x = 7/24
Step-by-step explanation:
elimination
12x + 4y = 1 | ×1 |
6x - 2y = 3 | ×2 |
12x + 4y = 1
12x - 4y = 6
_________--
8y = -5
y = -5/8
elimination
12x + 4y = 1 | ×1 |
6x - 2y = 3 | ×2 |
12x + 4y = 1
12x - 4y = 6
_________+
24x = 7
x = 7/24
