Answer:
x = 120°
Step-by-step explanation:
the 165 degree obtuse angle forms a straight line with the upper left angle inside the triangle, therefore this angle measures 15 degrees
we know two of the three angle measures so we add all three together to find the unknown angle
x + 15 + 45 = 180
x + 60 = 180
x = 120°

I have attached the graph of the question. So this is the graph of the question and i also attached the solved question screen shot.
I hope you get the idea. Thanks
Answer:
y = 5x2 + 10x - 15
We want this in format y = a(x-h)2 + k
where the vertex will be at (h,k)
y = 5(x2+2x) - 15
Complete the square on x2+2x
y = 5(x2+2x+1) - 15 - 5
We subtract 5 at the end because we are actually adding 5(1) = 5
so we need to remove it also to keep the total equal
y = 5(x+1)2 - 20
The vertex is at (-1,-20)
Answer:
The answer to your question is: Y = (13, -14)
Step-by-step explanation:
Data
midpoint = mp = (6, -3)
one endpoint = X = (-1, 8)
second endpoint = Y = (x, y)
Formula
Xmp = (x1 + x2) / 2
Ymp = (y1 + y2) / 2
Process
x2 = 2xmp - x1
y2 = 2ymp - y1
x2 = 2(6) - (-1) y2 = 2(-3) - 8
x2 = 12 + 1 y2 = -6 - 8
x2 = 13 y2 = - 14
Y = (13, -14)
I would distribute first.
Hope this helps.
頑張って!
