Answer:
37 degrees
Step-by-step explanation:
The tower and the shadow form legs of a right triangle. The angle of interest is the angle between a direct line from the shadow tip to the tower top, and the ground, adjacent to the shadow. The relevant trig relation is ...
Tan = Opposite/Adjacent
tan(angle of elevation) = (117 ft)/(158 ft)
The arctangent function is used to find the angle that has a given tangent.
angle of elevation = arctan(117/158) ≈ 36.52°
The angle of elevation is about 37°.
No it would have to be -50 to be a negative number.
Okay <em>we need to know the number of degrees in this shape first</em> in order to find x.
The formula to find the # of degrees in any polygon is
180 ( n - 2 )
n = the number of sides the figure has
This figure has 8 sides
180 ( 8 - 2 )
180 (6) = 1080°
This figure is 1080°
To find x, let's <u>subtract all the other degrees</u> they gave us
<em>1080° - 124° - 136° - 132° - 129° - 116° - 158° - 141° = 144°</em>
x = 144°
I hope I helped!
0,0 represent origin or rather it called origin
Answer: 2/3 hours
Step-by-step explanation:
okay so the speed now is 850, which is 850/340 = 2.5 times the original speed
Since It's 2.5 times the original speed,
2.5x = 5/3
so x = 5/3/2.5 = 2/3
