Step-by-step explanation:
Remember simple multiplication? Write the problem with 17 at the bottom:
8
* 1 7
----------
5 6 <-- this is 8*7
8 0 <-- this is 8*10 [we sometimes just shift and don't write the 0]
-------
1 3 6
So, 8*17 is the same as 8*10 + 8*7.
That is obtuse it doesn’t have equal sides
Answer:
Angle of elevation at which the balloon must take off in order to avoid hitting the tree is 5 degrees
Step-by-step explanation:
Given:
The height of the tree = 65 foot
The distance between the tree and the spot from which the balloon is launched = 250 yards
To find:
The angle of elevation at which the balloon must take off in order to avoid hitting the tree = ?
Solution:
Converting the yards to feet
1 yards = 3 feet
250 yards = 3 x 250 = 750 yards
Refer the below figure, The angle x is the angle of elevation at which the the ball must be thrown so that it does not Hit the tree

Substituting the values





-14x+6 is the final expression
