Answer:
X=1, i'm not sure if it's correct i didn't check it, okay i just plugged it in, x is = to 1
Step-by-step explanation: First you have to get the variable to one side of the equation by using the inverse operation of subtraction which is addition and add -3x to 6x making it 9x, then from there continue to use inverse operations.
Answer:
7m
Step-by-step explanation:
v=πr^2h
769.3=3.14*r^2*5
769.3=15.7r^2
769.3/15.7=15.7r^2/15.7
49=r^2
√49=√r^2
√49=r
r=7m
Three of the four towns are on the vertices of the triangle ΔCBD, through
which the bearing can calculated.
<h3>Response:</h3>
- The bearing of D from B is approximately <u>209.05°</u>
<h3>Method by which the bearing is found;</h3>
From the given information, we have;
AC = AB = 25 km
∠BAC = 90° (definition of angle between north and east)
ΔABC = An isosceles right triangle (definition)
∠ACD = ∠ABC = 45° (base angles of an isosceles right triangle)
![tan(\angle ABD) = \dfrac{45}{25}](https://tex.z-dn.net/?f=tan%28%5Cangle%20ABD%29%20%3D%20%5Cdfrac%7B45%7D%7B25%7D)
The bearing of <em>D</em> from <em>B</em> is the angle measured from the north of <em>B</em> to the
direction of <em>D.</em>
<em />
Therefore;
- The bearing of D from B ≈ 90° + (180° - 60.945°) = <u>209.05°</u>
