2.7m
Step-by-step explanation:
1.0m
0.5m
+1.2m
2.7m - answer
Step-by-step explanation:
the law of sines :
a/sin(A) = b/sin(B) = c/sin(C)
with the sides being opposite to the angles.
so,
14/sin(80) = x/sin(60)
x = 14×sin(60)/sin(80) ≈ 12.3cm
Answer:
![x^{2} - 5x - 24](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-%205x%20-%2024)
Step-by-step explanation:
( x + 3 )( x - 8 ) =
- 8x + 3x - 24 =
- 5x -24
Answer:
a straight line at an angle of 90° to a given line, plane, or surface.
Step-by-step explanation:
Answer:
The answer to the question provided is y = -3x - 12.
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
❃Incase you also forgot, what the slope formula is ☟
![m = \frac{y_2 - y_1 }{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%20%7D%7Bx_2%20-%20x_1%7D)
➊ First: We are going to be solving for the slope.
![m = \frac{ - 9 - 6}{ - 1 - ( - 6)} = \frac{ - 15}{ \: \: \: 5} = - 3](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B%20%20-%209%20-%206%7D%7B%20-%201%20-%20%28%20-%206%29%7D%20%3D%20%5Cfrac%7B%20-%2015%7D%7B%20%5C%3A%20%5C%3A%20%5C%3A%205%7D%20%3D%20-%203)
➋Second: We find the y-intercept.
![y = mx + b \\ 6 = - 3( - 6) + b \\ 6 = 18 + b \\ \frac{ - 18 = - 18 \: \: \: \: \: \: \: \: \: \: \: \: }{ - 12 = b}](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b%20%5C%5C%206%20%3D%20-%203%28%20-%206%29%20%2B%20b%20%5C%5C%206%20%3D%2018%20%2B%20b%20%5C%5C%20%5Cfrac%7B%20%20-%2018%20%3D%20%20-%2018%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%7D%7B%20-%2012%20%3D%20b%7D)
➌Third: Plug in.
![y = - 3x - 12](https://tex.z-dn.net/?f=y%20%3D%20%20-%203x%20-%2012)
