Answer:
5/6 (please give branliest)
Step-by-step explanation:
5/6 * 1/3 = 5/18
5/18 / 2/3 = 5/12
5/12 / 1/2 = 5/6

Answer:
cosA + sinA
Step-by-step explanation:
Using trig. identities :
cos(A + B) = cosAcosB - sinAsinB
cos2A = cos²A - sin²A
cos2A = (cosA + sinA)(cosA - sinA)
Therefore, your question is :
=> cos2A/(cosA - sinA)
=> (cosA + sinA)(cosA - sinA)/(cosA - sinA)
=> cosA + sinA

Answer: 33</h3>
=======================================================
Explanation:
The information that m || n is not needed or used, so I'm not sure why your teacher put that in there.
The angles shown are a linear pair. They are adjacent and they are supplementary. They form a straight angle.
Supplementary angles add to 180.
(x-17)+(5x-1) = 180
x-17+5x-1 = 180
(x+5x)+(-17-1) = 180
6x-18 = 180
6x = 180+18
6x = 198
x = 198/6
x = 33
---------
Extra info:
if x = 33, then,
- x-17 = 33-17 = 16
- 5x-1 = 5*33-1 = 165-1 = 164
Adding the angles gives 16+164 = 180 which helps confirm our answer.
Answer:
the area is originally 100cm
we can find the area by multiplying by the scale factro of 1/2
100 * 1/2
=50
so the new area is 50 square cm
