Step-by-step explanation:
X Y
--------
1 0.50
2 0.25
3 0.13
4 0.06
5 0.03
Length of x is 98.2 m
<u>Step-by-step explanation:</u>
Step 1:
Use the trigonometric ratio tan 27° to find the common side of both the right angled triangles.
tan 27° = opposite side/adjacent side = opposite side/9
∴ Opposite side = 9 tan 27° = 9 × - 3.27 = -29.46 m
Step 2:
Use this side and trigonometric ratio cosine to find the value of x.
cos 49° = adjacent side/x = -29.46/x
∴ x = -29.46/cos 49° = -29.46/0.30
= 98.2 m (negative value neglected)
Answer:
The solution is x=7
Step-by-step explanation:
We want to solve for x in the equation
![- 2x + 8 = - 6](https://tex.z-dn.net/?f=%20-%202x%20%2B%208%20%3D%20%20-%206)
Subtract 8 from both sides of the equation:
![- 2x + 8 - 8 = - 6 - 8](https://tex.z-dn.net/?f=%20-%202x%20%2B%208%20-%208%20%3D%20%20-%206%20-%208)
Simplify to get:
![- 2x + 0 = - 14](https://tex.z-dn.net/?f=%20-%202x%20%2B%200%20%3D%20%20-%2014)
This implies that:
![- 2x = - 14](https://tex.z-dn.net/?f=%20-%202x%20%3D%20%20-%2014)
![x = \frac{ - 14}{ - 2}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%2014%7D%7B%20-%202%7D%20)
![x = 7](https://tex.z-dn.net/?f=x%20%3D%207)
