Answer: 57.8512 feet (approx)
Step-by-step explanation:
Let h be the height of the stone face.
The angle of elevation from one sight to the bottom of face that is 750 feet far from the base of the mountain is 33°
⇒ The distance of the base of the stone face from the base of the mountain = 
The angle of elevation from another sight to the top of face is 36° that is also 750 feet away from the base of the mountain,
Therefore,
The distance of the top of the stone face from the base of the mountain = (h + 487.055694898) feet
By the trigonometry,
Therefore, the height of the stone face is 57.8512 feet (approx).

Step-by-step explanation:
How you find co-terminal is by adding or subtracting 360 degrees to the value you are given.
If it is a positive number like #18. all you do is subtract 510 - 360 = 150 until you get to a value between 0 degrees and 360 degrees.
The same thing applies to negative numbers. Like #21. You will add 360 + (-660) until you get to a number between 0 degrees and 360 degrees.
-660 + 360 = -300 (this is not a value in between 0 and 360 so we must add 360 again)
-300 + 360 = 60 (this is a value in between 0 and 360) (this is the co-terminal angle)
That is the idea of finding co-terminal angles.
Um answer f I don’t know math I’m really bad at it
Answer:
The first one is x = 19
The second one is x = 17
Step-by-step explanation:
The first one:
(4x + 3) + (x - 8) = 90 ---> becasue the angle is 90 degrees
substitute 19 and check
The second one:
(7x + 10) + (3x) = 180 ---> because the angle is 180 degrees
substitute 17 and check
Hope this helps! :]
