I use my calculator
Y1 (the blue one) = x^2-2x
Graph
2nd trace minimum
X= 1 and y = -1
So the vertex is (1,-1)
Angle O=64
Side m=7.3159882(rounded if needed)
Side n=16.68902(round if needed)
We are given
Angle M which equal 26.
Angle N equals 90 degrees
Side MN which equal 15.
We are asked to find all the missing elements of the triangle.
- Angle O can be found using triangle interior theorem so we can add 90+26+x =180 to find the value that satisfies the x value.
Angle O=64 degrees
We can find side m by doing law of sines.
which is 7.315(round if neeeded).
We can find side n using pythagorean theorem,
Side n=16.689(round if needed)
A)15000 x (9 : 100) x 3 = 4050
B) 15000 + 4050 = 19050
I hope it is correct ❤️
