Answer:
<h2>BC = 25</h2>
Step-by-step explanation:
It's an isosceles triangle (congruent angles ∠C ≅ ∠B).
Therefore AC = AB.
We have the equation:
<em>subtract 1 from both sides</em>
<em>subtract 2x from both sides</em>
<em>divide both sides by 2</em>
Substitute the value of <em>x</em> to the expression BC = 3x - 8:
Answer: The answer is 25.125
No there's a difference between it, I know what it was on the tip of my tongue but I forgot it <span />
Answer:
x = 4 sqrt(5)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 + x^2 = 12^2
64+ x^2 =144
Subtract 64 from each side
x^2 = 144-64
x^2 =80
Take the square root of each side
sqrt(x^2) = sqrt(80)
x = sqrt(16*5)
x = 4 sqrt(5)
Answer:
24,800 meters
Step-by-step explanation:
We basically have to convert km to m, or kilometers to meters. For this we need the conversion factor:
1000 meters = 1 kilometers
So change from kilometers to meters, we simply need to multiply by 1000. Thus, we would have:
24.8 km * 1000 = 24,800 meters
Thus,
24.8 km = 24,800 m
