Answer:
n=-4/3
Step-by-step explanation:
So the equation is -2/3n+7=15
First you subtract 7 from both sides: -2/3n+7-7=15-7 : -2/3n=8
Next multiply by 1/-2 on both sides, canceling out the -2 on the left and dividing 8 by -2 on the right: 3n=-4
Next divide by 3 on both sides
Answer: n=-4/3
Answer:
415.8 meters
Step-by-step explanation:
We know the adjacent and the opposite, so we will use tan
tan 22 = opp/ adj
tan 22 = 168/x
x tan 22 = 168
x = 168/tan 22
x =415.81459
Rounding to the nearest tenth
415.8 meters
X=15. This is the Altitude theorem which is Altitude/Part = Altitude/Other part. In this question you would set up the proportion 9/X = X/25 and multiply cross products to get 225=X^2. Then you undo X^2 by doing the square route of 225 and then you get 15 as the final answer.
