Attached you will see the solution using the trig plane and general solutions.
Try using photomath it will explain on what to do.
Answer:
True.
Step-by-step explanation:
By definition of a mid point, it is located in the middle of two connected points. This means that the split is equal on both sides.
IF X is the midpoint of ZW, then ZX = XW.
~
For this case what you should do is use the following trigonometric relationship
senx = (1200) / (2400)
senx = 0.5
Clearing the angle we have
x = ASIN (0.5)
x = 30
Answer:
The angle of elevation from the base to the top of the mountain is 30 °
Answer:
ST = 7.07 units
Step-by-step explanation:
* Lets explain how to find the length of a segment
- The length of a segment whose endpoints are 
and
can be founded by the rule of the distance

* Lets solve the problem
∵ The line segment is ST
∵ S is (-3 , 10)
∵ T is (-2 , 3)
- Assume that S is
and T is 
∴
and 
∴
and 
- By using the rule above
∴ 
∴ 
∴ 
∴ 
∴ ST = 7.07 units
