We know the rate of the change, 3 meters per hour. And we want to know how long it will take to reach 12 meters. Say we need to reach 6 meters instead 12.
How long will that take? 2 hours! Because we divide 6 m by 3 m/h.
Now let us do the same thing will 12 meters.
12 m / 3 m/h = 4 hours
It will take 4 hours to reach the 12 meters height.
We must infer that these are the angle measurements. If so, then there will be an infinite amount of solutions because we can scale a triangle with those angle measurements to a different dimension. I hope this helps! -Dan<span />
Answer:
X=16
Step-by-step explanation:
7(4 - x) = -84
7*4=28 7*-x=-7x so
28-7x=-84
subtract 28 from -84
-7x=-112
now divide it all by -7
x=16
Answer:
9/4 (Answer 2)
Step-by-step explanation:
Take half the coefficient of x and square that result:
(1/2)(-3) = -3/2
Squaring this, we get 9/4 (Answer 2)
