Answer:
The first one- 24, The second one-B
Step-by-step explanation:
The first one-Top corner=110, 110+46=156, 180-156=24
The other one-I have no clue how to explain it
Answer:
c) if x=2, then 4x=8
Step-by-step explanation:
Answer:
1 − 2 cos x
Step-by-step explanation:
y' = 2 sin x
y = C − 2 cos x
1 = C − 2 cos(π/2)
1 = C
y = 1 − 2 cos x
They are vertical angles and would be the same so set them to equal each other and solve:
3x-4 = 2x+9
add 4 to both sides:
3x = 2x +13
subtract 2x from each side:
x = 13
now replace x with 13 in the original equations:
3x-4 = 3(13) -4 = 39-4 = 35
2x+9 = 2(13)+9 = 26+9 = 35
the angles = 35 degrees
