x = 130 is your answer
130 - 20 = 110
Since line E and F are parallel and are straight lines, we know both angles will add up to 180°
110 + 70 = 180
Answer:
true
Step-by-step explanation:
1st :The angle of depression 30° = the angle of elevation (from the truck to the height of the building.
2nd :
cos 30° = (adjacent side)/(hypotenuse)
cos 30° = x/100, but cos 30°= (√3)/2
(√3)/2 = x/100 and x = (100√3)/2
and x = (50.√3) = 86.60 m
Answer:
Compound Interest= $3440
Final Amount= $5440
Step-by-step explanation:
Compound Interest's formula= P(1+r/100)^n
where P is Principal, r is Rate then n is Years
So in this case,,2000(1+.72)^1 = $3440
Hence, Total Amount = Principal+Interest
therefore T.A= $2000+$3440
T.A=$5440

Answer:
B) 116°
Step-by-step explanation:
y=180-54-64=62
x=180-62-64=54
62+54=116
