I think its A but not positive
Step-by-step explanation:
iii=90
41+i=90(opposite angle)
i=90-41
i=49
26+ii+49+41=180(straight line angle)
116+ii=180
ii=180-116
ii=64
50+25+iv=26+64(opposite angle)
75+iv=90
iv=90-75
iv=15
55+i+55=180(straight line angle)
110+i=180
i=180-110
i=70
ii=55(alternative angle)
Answer: y=-4x+7
Step-by-step explanation: Move 8x to the right side to isolate y. 2y=14-8x. Divide the whole equation by 2 to get y by itself. y=7-4x
Answer:
14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km
Answer: x = 2
Step-by-step explanation:
First, Distribute
-2+8x=3x+8
Then, Subtract 3x
-2 + 5x=8
Then, Add 2
5x=10
Then, Divide by 5
x=2
Hope it helps <3
