|7-(24÷|3-6|)|
|7-(24÷|-3|)|
Now we have to get the -3 outside the 2 Lines but the lines are saying that if the number inside is negative when you get it outside it has to be positive.
|7-(24÷3)|-
|7-(8)|
|7-8|

The height of the ceiling is 162.31 meters
The situation will form a right angle triangle.
<h3>Right angle triangle:</h3>
Right triangle has one of its angles as 90 degree. Therefore, the sides can be found using trigonometric ratios
The triangle formed, the theodolite distance from the spotlight is the adjacent side. Therefore,
tan 62.7 = opposite / adjacent
tan 62.7 = x / 83
cross multiply
x = 83 × tan 62.7
x = 160.809554025 m
Therefore, the height of the ceiling form the ground is as follows:
- 160.809554025 + 1.5 = 162.309554025 m

Answer:
Step-by-step explanation:
2x²-13x+21+6x²+29x-5
=8x²+16x+16
50 = x^2
To isolate x you need to do the opposite of an exponent, which would be square root.
![\sqrt{50} = x Next solve what the square root of 50 is[tex]5\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B50%7D%20%3D%20x%20%3C%2Fp%3E%3Cp%3ENext%20solve%20what%20the%20square%20root%20of%2050%20is%3C%2Fp%3E%3Cp%3E%5Btex%5D5%5Csqrt%7B2%7D)
= x
That is the exact form, in other words your answer, if teacher is looking for a decimal, it would be
7.07 = x
