Answer:
Step-by-step explanation:
Step one:
given data
3,700 mile
In scienctific notation or in standard form 3,700 mile is expressed as
4/5 x55
=4/5*55/1
=(4*55)/(5*1)
=220/5
=44/1
=44
Answer:
You got it right. Triangle DAC
Step-by-step explanation:
Line segment DA is a perpendicular bisector(it cuts line segment CE perfectly in half making line segment AE an CA congruent. Since the triangle share line segment DA that makes them congruent by the SAS postulate
This is a 30-60-90 triangle
opposite side of rigt angle=2x
opposite side of 60 degrees is x√3
opposite sides of 30 degree is x
the right angle is at the base of the building so therefor
200=x
2x=distance from surveor to top of building and x√3=height of building
x=200
200√3≈346.41
the answer is 346.41 feet
