Answer: 68 degrees
To get this answer, you multiply 34 by 2 to get 34*2 = 68. I'm using the inscribed angle theorem. This says that the arc measure is two times that of the inscribed angle, where the inscribed angle cuts off the arc.
Answer:
b)
Step-by-step explanation:
Surface area of a cube = 6a² , here a is the side of cube
When side is halved, side = a/2
Now, the surface area of new cube = 6* (a/2)²
= 
= one fourth of the cube
Answer: Horizon is 35777.64 m away from observation deck.
Step-by-step explanation:
Since we have given that
Height of tower above ground level = 200 m
Radius of earth = 6400 km
Let R be the radius of earth.
Let the height of observation and
Let d be the distance from observation deck to horizon.
so, it makes a right angle triangle.

Hence, horizon is 35777.64 m away from observation deck.
