Answer:
(4,-7)
Step-by-step explanation:
-w=(5,-3)
-z=(-1,-4)
so -w-z=(5-1,-3-4)
Answer:
x = 10
y = 6
Step-by-step explanation:
<u>Vertical Angle Theorem</u>: When two straight lines intersect, the opposite vertical angles are always equal to each other.
⇒ m∠1 = m∠3 and m∠2 = m∠4
⇒ m∠1 = m∠3
⇒ 10x = 100
⇒ x = 10
<u>Linear pair:</u> Two adjacent angles which sum to 180°.
⇒ m∠1 + m∠2 = 180°
⇒ m∠3 + m∠4 = 180°
⇒ 100 + 10y + 20 = 180
⇒ 120 + 10y = 180
⇒ 10y = 60
⇒ y = 6
$13.68 because you do [.18+.06=.24] [18•.24=4.32] [18-4.32=13.68]
Answer:
Triangle
Step-by-step explanation:
A triangle has three vertexes, and therefore three interior angles. Those angles also sum to 180 degrees because of the formula (n-2)*180, where n is the number of sides that a polygon has. Plugging in 3, you get 
, or just 180 degrees. Hope this helps!
Answer:108
Step-by-step explanation: divided 81 and 3. the answer is 27. multiply 27 x 4 you get 108.
