Answer:
I had done rough method on the page
Step-by-step explanation:
I think first once is correct ...
Both sides need to equal 180 (The side with the 90 degrees measurement and the side with equations). So first subtract 180 from 90
to get the measurement of 5x and you get 90 but we aren't done yet since we need to find x so now we need to divide 5 by 90
and we get 18 which is X.
Now we need to find the measurement of Y. Now both angles on that side together equals 180 so we need this equation.
First, distribute 5(y + 11)
Then you get this equation :
Now, add the two equations together
and you get this equation
Now subtract 45 from both sides
and divide by 9 on both sides
and you get your answer
So
and
Answer:
x = 9.7
Step-by-step explanation:
The area of a triangle is A = b * h / 2 where A, b, and h are the area, base and height respectively. We know that A, b, and h equal 47, x, and x respectively so we can write:
47 = x * x / 2
47 = x² / 2
94 = x²
x = ±√94
In context, x can't be negative so the answer is x = √94 = 9.7.
Answer:
When the solution is negative
Step-by-step explanation:
One example, let's say you are buying pens and each pen cost 3 dollars and you cannot spend more than 15 dollars, how many pens can you buy?
The inequality would be 3x < 15, so any negative solution is not reasonable because you cannot buy negative pens. The same goes for most real-world problems dealing with time, money, or distance.
Answer: amplitude
Step-by-step explanation: The amplitude represents half the distance between the maximum of a sine or cosine graph.
