complementary angles sum up to 90°.
so if one of them is 43°, then the other is just 90 - 43 = 47°.
Answer:
Distance between point
and midpoint of line joining
and
=
units.
Step-by-step explanation:
Given:
Points:
![A(3,4)\\B(8,10)\\C(4,6)](https://tex.z-dn.net/?f=A%283%2C4%29%5C%5CB%288%2C10%29%5C%5CC%284%2C6%29)
To find distance from point A to midpoint of BC.
Midpoint M of BC:
![M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%5Cfrac%7By_1%2By_2%7D%7B2%7D%29%5C%5C)
[Plugging in points
]
![M=(\frac{12}{2},\frac{16}{2})\\](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7B12%7D%7B2%7D%2C%5Cfrac%7B16%7D%7B2%7D%29%5C%5C)
![M=(6,8)\\](https://tex.z-dn.net/?f=M%3D%286%2C8%29%5C%5C)
Distance between A and M:
![D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D%20%5C%5C)
[Plugging in points
]
![D=\sqrt{(3)^2+(4)^2} \\](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%283%29%5E2%2B%284%29%5E2%7D%20%5C%5C)
![D=\sqrt{9+16} \\](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B9%2B16%7D%20%5C%5C)
![D=\sqrt{25} \\](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B25%7D%20%5C%5C)
![D=\pm5](https://tex.z-dn.net/?f=D%3D%5Cpm5)
Since distance is always positive ∴
units
